Hello everyone. I have not played since 5th edition.. My buddies and I are getting back in,and in doing so I've chosen chaos marines. Now in building my list I notice I'm seeing some new rule phrases such as "Each time an attack is made with this weapon,subtract 1 from that attack's hit roll" I think I understand this as :If I need 3's to hit..using said weapon, now I need 2's: Is that correct? Thank you for any help given. If I am wrong please please tell me! lol. (have no picked up the rulebook yet. got the combat patrol and codex first,rulebook is next paycheck)

No. In 5th edition the big slow weapons had that you fight in Inisiative 1. Since Inisiative is gone they now make it worse to hit. This would be power fists, hammers etc. Beeing unvieldy does not make it easier to hit. It makes it harder

The wording can be a bit difdicult, but once you get into it it is OK.

Ok if I may ask, how does that math work then. I remember it being the lower your to hit number is the better. This is why I am confused.

You're not reading it correctly

You have your to hit value, and your hit roll. You compare one to the other.

When you reduce the hit roll by 1, that turns a 3 into a 2. If you needed a 3+ to hit, you've now missed.

Don't skip the starter pages. This game is VERY different to 7th and before.

It is still "the lower your to hit number is the better"

But now you do not compare Weapon skills or consult that gigantic chart.

If a Dataslate for a model shows a 3+ weapon skill, then you need to roll a 3 or more to hit.

If you roll a three for said model, but have a "subtract 1 from that attack's hit roll" on a weapon, you take that 3 you rolled, and it becomes a 2. comparing that with the 3+ 3+ weapon skill, you see that you have missed.

On the other hand if you have a 4+ weapon skill, and a +1 to your hit roll, you can roll a 3, add 1 and compare that with the models weapon skill of 4, and see that you now hit.

TLDR The Weapon skill of the model does not change, if your model has a +1 or -1 you have to add or subtract from the hit roll (Which is the die result for that attack).

If a rule says to subtract from a roll, then it means you need to take the number you rolled on the dice and subtract from that.

e.g. if you attack with a power fist and roll a 3 to hit, then it's the same as if you had rolled a 2.

Side note, dice rolls to hit and wound cannot be modified by more than 1. First, you calculate any + and - to hit (+3 to hit and -1 to hit is +2 to hit), and if the result is still more than 1, you round it down to 1.

As another oldie, if it helps, you can mentally do the reverse of the change to the stat. So a 3+ to hit with a -1 on the die roll is a (bad) +1 to the stat, i.e. needs a 4+ to hit.

You can't use this in reality all the time, because rolls can't be lowered below a 1, and a 1 always fails (so the best you can ever have for armour saves is a 2+ for example). And there are other modifiers that can apply to a roll based on other rules.

But I find it helps me to think "I need to roll a 4 or higher for the guy with the power fist, 3 or higher for the rest" in simple circumstances.

That's dangerous with reroll misses...

Off hand, reroll failed... has been removed from the game, as it was...well, a bit stupid. You now just get rerolls of to hit or wound and you can choose
