@Catbarf: How do you feel about the classes weapons and saves in the later Epic games, like Epic Armageddon? Because there's a good deal of "exceptions" and then "ignoring-of-exceptions" with Reinforced Armor, Macro Weapons and Titan-Killer Weapons (plus Invuln saves and Void Shields too). On the one hand it sounds goofy when you explain it (Reinforced Armor saves are re-rolled, unless hit by a Macro Weapon, in which case they're taken only once, unless it's hit by a Titan Killer weapon where saves are not taken at all, unless it's an Invuln save.) But I find it works well in practice, partly because most of the time only a few models are ever benefitting form any of them. I guess also because there's a minimum of additional rolls.

I say this realizing my usual opponent plays a Grey Knights list where Terminators have Reinforced Armor and then a 6+ Invuln. Then again they are only four models for 400ish points, where as my IG Mechanized Company has like. . . 20 models at 400. And of course they had no fancy rules, they just save or they die. In fact by default the Infantry get no save at all.

Actually, it's almost like there's a design metric of number of dice per point in a unit. The cheaper a unit/model is the fewer dice there should be to roll, just so that you're not spending so much time of bunches of little models. By this metric Feel No Pain should almost never be on cheap models because it's an additional roll and risks becoming burdensome.

Similarly, physically putting my models up on a rooftop and rewarding them for exposing themselves and seeking thath better positioning is way more appealing to me than a lieutenant giving his squad Lethal Hits because he yelled the words, "Aim better!" at them.

Okay, so since not all rpg's are equal, so let me define my terms: I'm talking pen and paper only, an the games I know most extensively are: Dungeons and Dragons, World of Darkness, Cyberpunk and Shadow Run. Of all these games, the only one that made much use of positioning tools like models or markers was D&D 3 and 3.5. Now, that's not to say that there aren't SOME positioning rules common to all classes (or Clans, or Archetypes, etc) that exist in the rules of RPG's but they are quite limited. SO D&D, even editions that didn't support the use of models, still had bonuses for flanking, assisted actions, and tactics like the elevated firing positions you mention, or sending fighter sub-types to engage melee opponents in order to protect casters and ranged fighters.

But even these often interacted with class specific rules. So yeah, you say "D&D had positioning rules"- but backstab is thief class ability, whirlwind attack is a fighter ability and touch spells can only be used by spellcasting classes... So what's a pure "positioning rule" without those class based modifiers?

Accomplishing the same result different ways for no reason other than to make the execution feel different isn't a feature of RPGs, it's a feature of bad RPGs. D&D would not be a better game if Barbarians got half as many hit points as Fighters but a 11+ save on D20 against each point of damage. And it would absolutely be a worse game if that was the distinguishing factor between the two classes- not actually mechanically impactful differences in their capabilities, just a wholly superficial difference in resolution, in the misguided belief that rolling dice differently will make them feel different when the end result is functionally the same.

It seems to me that the whole crux if this paragraph comes down to how we define "mechanically impactful differences in capabilities." Personally, I DO see the differences between T, W, Sv, FNP and Invul as mechanically impactful differences in capabilities. I may disagree with the way GW assigns these to specific units, but they DO mean different things to me:

An Invul is anything that prevents an attack from making kinetic contact with the model; an attack resisted this way doesn't hit, which is WHY armour penetration is irrelevant
A SV can resist anything that hits the model.. But because the attack DOES hit, the power of the attack (AP) can modify the level of protection
Toughness is natural armour or strength of will which prevents someone from being injured by an attack
FNP is an insensitivity that prevents someone from being affected by damage from an attack- they take the damage, but manage to shrug it off for the remainder of the battle
Wounds indicate that a unit can maintain combat effectiveness despite horrendous damage

IMHO these are (ideally) the "fluff" reasons why the mechanics exist, and what they are meant to represent. I think we can certainly argue that there may be different ways to represent these characteristics; I think we can argue whether GW distributes these abilities according to these characteristics, and I think we can argue about tweaks to these mechanics or how they are used that would improve the connection between the "fluff reason" and the mechanic that reflects it.

But my post was a response to someone arguing to cut a whole mechanic... Which would impact GW's ability to represent one of the conditions listed above,

I will again point out that when we are discussing 40K, we are talking about a game with a half dozen different ways to model 'this guy is hard to hurt', but no core mechanic for modeling 'this guy is hard to hit', which instead requires kludgy to-hit penalties or invulns patched onto the core combat resolution. Given that there are several factions that have speed-as-defense as part of their identity, it seems a glaring omission that having supernatural reflexes is mechanically represented the exact same way as an energy shield, especially if you put so much stock into differences in mechanical resolution as a means of conveying fluff.

As I explained above, to me invul mechanics as is DO feel like a good way to represent dodge. I agree that "fields" being included in "fluff reasons" for invuls somewhat clouds the issue, but only somewhat: a field DOES interpose itself between the attack and the target, rather than mitigate the effect of the attack after it makes contact.

 catbarf wrote:

So I don't really buy that having Toughness and Wounds and armor saves and invuln saves and penalties to wound and FNPs is essential in order to make factions feel different from one another. I bet you could consolidate defensive stats a lot and use some of that design overhead to represent literally anything else that differentiates the factions besides how well they take a punch, and it'd be a net positive for faction identity.

Based on everything else I've said in this response, it might surprise you, but I do kinda agree with this. I'm not arguing that these specific mechanics are NECESSARY as much as I'm arguing that efforts to reduce the mechanical complexity of the game often come at the expense of meaningfully differentiating between factions. I'm really just saying that care has to be taken to prevent that.

If you look back through the thread, there will be comments that resemble this analogy:

Differences between rangers, fighters and barbarians just complicate the soldier archetype; differences between Wizards, Sorcerors and Bards just complicate the magic user archetype... The only classes should be fighter mage cleric thief. The game would be simpler and I wouldn't have to buy as many books or memorize as many rules.

And yeah, there was an edition of D&D that did that, and yeah I played it and yeah it SUCKED compared to almost every other edition of D&D.

I think its just a debate over whether dice rolling really forges a narrative - or whether its just a computation exercise.

I mean when I was younger I perhaps had much more imagination, and all these little things did matter. The game was something of a story told in each dice roll.

Whereas now... not so much. The game is a game "as a game". If I tell unit A to shoot at unit B, I just want to know how many - if any - I kill or how many wounds I do. There's not a lot of interest in how many shots missed, how many failed to wound, how many were saved by armour (or invuls) and then how many would have died but they shrugged it off because of some special resilience. In terms of my next decision its all the same.

But equally, I want the game to feel somewhat like the fluff - and I find thing like one page rules strip far too much away. It may be noise, but it does... build a picture. Bolt Action for example "works" - but without all the noise to cling to, I find it very difficult to feel much about the various factions. "You should play British because you are British" - well that's a bit boring.

I've bolded what I'd consider the biggest issue.

If Toughness accounts for a model's armour then what exactly is the point of having a separate save for armour? Especially in an already-bloated wargame. Hell, even many RPGs like Dungeons and Dragons often don't make this distinction!

I know you can probably argue that toughness is inherent but this just feels like an unnecessary (and often meaningless) distinction. Take races like Tyranids and Necrons, how do you meaningfully separate armour from just being part of their bodies (i.e. toughness)? Same goes for vehicles and dozens of other units.

Put simply, armour should just factor into how tough a model is.

Imagine for a moment if models had a 'Dodge' characteristic that represented their agility. Instead of WS/BS being flat to-hit values, they're compared against the enemy Dodge value. Then, on a hit, you roll S vs T. And then any successes inflict wounds.

Maybe a few models like characters could get an invulnerable save, but most models have no save at all - just dodge and toughness (with Eldar and Skimmers having higher dodge, while tanks and armoured infantry have higher toughness).

@vipoid - It is true that the distinction between Natural Armour and Armour is less of a distinction than the other distinctions on the list. If I was going to tweak anything, this might be where I'd start.

But D&D, or at least several editions of it, DID make a distinction between armour and natural armour; the former doesn't limit dexterity based AC bonuses but the latter does. And of course, D&D, because it incorporates non-combat mechanics, presents other differences, such as donning and doffing rules don't apply to the former, nor do repairs; natural armour can't be enchanted as an item, etc.

I think you misunderstood my point slightly (perhaps I didn't explain myself well?)

Yes, some editions of D&D distinguish between armour and natural armour. However, they both just add to the same value 'AC'. So, regardless of whether a given creature has armour, natural armour or whatever else, there's still only ever one roll involved to see whether or not an attack injures it.

By contrast 40k has separate rolls for 'natural armour' and 'armour'.

Warp spiders suddenly moving to a new position when targeted? Fluffy. Conveys the idea that they've hastily teleported to relative safety. Presents the opponent with a bit of a puzzle to plan around. Where do they need to put their units in the movement phase so they can deal with the spiders changing position?

Lieutenants granting marines lethal hits? Kind of boring. Why are marines only good at aiming their guns when the boss is standing next to them chastising them about proper bolter discipline? Doesn't really change the way the unit behaves other than making them do more damage.

To me, the spider mechanic feels like it's telling a story while the lieutenant mechanic feels like it's just a generic, gamey damage boost. And not even a themed one.

Lethal Hits specifically is also capable of taking stuff that shouldn't be doing much into actual threats.

Sustained Hits 1 on a BS 3+ gun is (assuming you only crit on 6s and have no bonuses or penalties to the hit roll) a 25% increase in damage on average. This is true whether you're firing Bolters into Termagants, or a battery of Lascannons into a GUO.
Lethal Hits on a BS 3+ gun is (same assumptions as above) anywhere from a less than 5% boost (wounding on a 2+ is 5%, add on Twin Linked and it's now less than a 1% boost) to more than doubling your damage (wounding on a 6+, no rerolls).

I don't mind rules that vary in effectiveness-but I'd like there to be an in-universe reason for the different effectiveness.

There's an old saying, "mod edit - removed". You are not comparing apples and apples. Sustained Hits (when only critting on a 6) adds a hit ~16% of the time. I'm not sure how something that only adds 16% at the top of the stack adds 25% at the bottom of the stack, but sure. Sustained Hits does not care about BS skill. It just triggers on a crit hit (default 6+ or 16%) Additionally you do not involve the damage roll in Sustained Hits. 16% more hits do not equate to 25% more damage, especially when hits that cause damage is less than 100%. 16% multiplied by less than 100% is going to be less than 16%. The Aggressor bomb was based on stacking Sustained and Lethal to generate more hits and Lethal hits than than the on-paper number of attacks. Crits were moved to a 5+ which means for every miss (1-2 on a 3+) you got one bonus (sustained) hit AND one bonus (lethal) hit per miss - on average.

Do not call me a liar.

As far as I can see JNA's maths is correct.

Say you have 6 shots hitting on 3s. You'd expect to get 4 hits.
You now get sustained on 6s. You still get your 4 hits, but 1 of those hits is a 6, so 5 hits. This is a 25% increase.

The thing is though if you were hitting only on 6s, you'd get a 100% increase. Its just that typically you don't see this scenario.

By contrast if you were hitting on 3s and wounding on 6s, lethal hits adds 125% to your damage as can be seen below:

So hitting on 3s, wounding on 6s.
36 shots, 24 hits, 4 wounds.
With lethal. 36 shots, 6 auto-wounds, 18 regular hits, 3 normal wounds. 9 total wounds. So 5 extra wounds.

Its not a 25% increase in damage. And its not even a 25% increase in hits. Its a 16% increase in hits - which will be decreased by rolling to wound, and then by armor and other saves long before you get to damage. Because you only got one hit over the 6 shots its 16%. 1 divided by 6 is 16%. You roll that one shot 6 times, you get 1 extra hit. You roll six shots once, you get one extra hit. On any given attack roll, you get a bonus hit 1 out of 6 times. Its only a 16% chance of getting an extra hit per attack. A 25% increase in damage will require significantly more than a 25% increase in hits. At the bare minimum a 25% increase in damage - for BS3, wound on 4's would require 50% more hits. Sustain'ing on a 4+ so that half of them will wound for 25% - and the target can't have a save. Lets say you're talking about an Intercessors into a Legionary. Bolt Rifles have a -1, to the Legionary's 3+ Armor so 50/50 turning a wound into a damage. That means 25% more damage means 50% more wounds. Wounding happens 50/50 so you need 50% more hits than you "need" damage or 100% more hits which is then halved into 50% wounds, halved into 25% more damage. Assuming there isn't a Feel No Pain.

Edit to Add: Lets do it backwards that may make it easier to understand. You roll those 6 shots. You get your one six. 84% of your rolls were not a 6 and did not give you more hits. 100% - 84% is 16%.

If you have 36 AP-1 Bolter shots (say, an Intercessor Squad who lost one guy) hitting on a 3+ you will do an average of 6 wounds to MEQ.
If you add Sustained Hits 1, you do an average of 7.5 wounds.

What is 7.5 divided by 6?

Damage, not Wounds.

If you have 1 Lascannon shooting into one Grot you do just over half a damage. If you give that Lascannon Sustained Hits you do just under 2/3 of a damage. What is the difference between 3/6 and 4/6?

A Lascannon that hits on a 3+ does an average of 5/18ths a point of damage to a Grot. 2/3rds of a hit times 5/6ths of a wound, no save, max damage of 1.
If you give it Sustained Hits 1, it does 25/36ths a point of damage to a Grot. Average of five hits per six shots so 5/6ths times 5/6ths, no save, max damage of 1.

Sustained Hits damage bonus scales based entirely on the initial hit rolls. At SH1, it's a 20% boost on 2+, 25% on 3+, 33% on 4+, 50% on 5+, and 100% on 6+.

You roll 6 Dice. 5 do not generate an extra hit. One does. What is 1 divided by 6?

1/6th. You're asking the wrong question, though.

Every six shots, if you hit on a 3+, you get an average of 4 hits. If you have SH1, you average to 5 hits instead.

And that hit has to spread out over 6 shots. 1/6th of a shot. Any given shot only has a 16% chance of giving you the extra hit. Which is still a long long ways away from damage.

FNP should not be in the game at all ever under any circumstances so long as units of multi-wound models and multi-damage attacks exist. Creating a game state that prevents fast-rolling in a game on the scale of 40k and forces you to resolve damage one shot at a time is pointless game slowdown.

Devil's advocate: Do we really have a clear of what 40k's scale really is though? I know tournaments lean towards 2k games where FNP can bog things down if available en masse, but I don't generally feel like the game is slowed down significantly by a handful of units having it, and 1k games tend to move quickly enough that a tiny bit of slowdown isn't a big deal.

Multiplication is commutative. A 25% increase in hits is a 25% increase in damage. It might be a 25% increase on a very small number, depending on wound rolls and saves, but it’s still a 25% increase.

And Sustained is not independent of hits, which is why it’s not a 16% increase - a miss is still a miss. For something that hits on 3+ sustained occurs 1/4 times you hit (a 6 out of 3,4,5,6), so it’s a 25% increase in hits. For something thats hits on 6+ (e.g. overwatch) it’s 100% of hits that trigger sustained so you double your hits and double your damage.

Funnily enough the one that always is a 16% increase is re-rolling 1s. That one is independent of BS (but full re-rolls are not).

It's funny how much of statistics is a matter of perspective.

Sustained Hits always provides a consistent boost of absolute output (IE, for every 6 dice you throw, you can expect one bonus hit).
But the relative boost to output changes based on how good the output was to start with. If you started with 5 hits, an extra one feels smaller. Whereas if you started with only 1 hit, that bonus hit makes a huge relative difference.

Reroll 1s on the flipside always provides a consistent relative boost, but the absolute boost differs. 36 shots with reroll 1s will result in 5 bonus hits if you're BS2+, but only 1 extra hit if you're BS6+ (vs a consistent 6 bonus hits for Sustained Hits).

People usually talk in relative terms, but both are useful in their own rite and in combination.

I think reroll 1s is interesting in the second order effects.

I.E. in mathhammer its a flat 1/6th increase in the expected number of hits. But in practice its great protection for "that time" your 2+/3+ unit rolls a disproportionate number of 1s. You are arguably less interested in the output increase, than the reduction is chance of absolute failure from attacking unit X or Y.

Whereas if say you are only hitting on 6s, in theory reroll 1s increase your odds the same, but in practice your odds of failure are so high anyway you can't usefully rely on it.

Arguably this is true in general for Sustained/Lethal - because it allows you to "get lucky". But the statistics are harder to crunch than simple mathhammer.

Arguably though this is why FNP is so good/so annoying to play against. You can say a 6+++ is pointless - but some games you just kept rolling them. In the games where you never rolled them, you just sort of shrug it off because its a 1/6 chance and what do you expect? Its giving your opponent that extra chance of failure.

There's definitely a difference in the variance yeah
Reroll 1s lowers your variance as it increases your average by lifting up your failures (IE a miss becomes a hit)
Sustained Hits increases your variance as it increases your average by further boosting your successes (IE a hit becomes two)

1/6 chances especially can really spike sometimes.
But then so can any dice poo. 8 dead marines on 8 armour saves? Definitely happens

FNP should not be in the game at all ever under any circumstances so long as units of multi-wound models and multi-damage attacks exist. Creating a game state that prevents fast-rolling in a game on the scale of 40k and forces you to resolve damage one shot at a time is pointless game slowdown.

Devil's advocate: Do we really have a clear of what 40k's scale really is though? I know tournaments lean towards 2k games where FNP can bog things down if available en masse, but I don't generally feel like the game is slowed down significantly by a handful of units having it, and 1k games tend to move quickly enough that a tiny bit of slowdown isn't a big deal.

Shoot one unit with a high volume of d3-damage shots at one multi-wound unit with a FNP, and then come back and tell me you felt like that was a good use of time in any size of game.

Another thing about FNP?

40K has rules for [jazzhands]Drama and Narrative[/jazzhands]

FNP is one of those. It’s the abstraction of some beasties and warriors being so resilient, through sheer size, supernatural blessings or built in auto healing tech, that they can survive otherwise entirely fatal wounds. But, without making them unkillable in practice. And in a way simply giving them more wounds or a higher toughness doesn’t.

It’s a way to fox pure mathhammer results.

I’m not saying therefore any “oh for heaven’s sake, you made three out of three FNPs and now I need to shoot it again” feels bad moments are invalid. Just that by adding it as a further layer of resilience, it more accurately portrays that sometimes, something’s just feel impossible to kill.

The problem of course is that [jazzhands]Drama and Narrative[/jazzhands] rules are applied inconsistently.

Maybe the most infamous example was Plague Marines losing their FNP. Their lore didn't change, but how they feel on the table did. If we go deeper into classichammer, IWND and FNP were basically the same lore but with vastly different gameplay implications (and FNP was outright superior), which lead to inconsistencies between lore and gameplay.

So we run into the issue that some big and resilient units have FNP and some other big and resilient units do not, because vibes of the rule writers rather than any real abstraction.

I'll also note that I put less value in FNP as a way to shake up the math because we already have to-hit, to-wound, save, and potentially Damage rolls to add randomness to how effective our attacks are.

So if you look at it as more rolls = more chances for something unlikely to happen, we already have plenty of chances for un/lucky rolls to occur.

And if you look at it as more rolls = more likely to adhere to the bell curve, then we already have so many rolls in the attack process that FNP doesn't strongly impact how random the end results look. At least not FNP5+ or 6+.

I do get the notion of FNP being a way to make fleshy units feel more tough and chewy though.

I believe this was mentioned earlier, but it also makes regeneration stronger.
Regaining d3 wounds on a 24 Wound model isn’t quite as good as regaining d3 wounds on a 20 Wound 6+ FNP model.
