Adding Whirlwinds to my army for the first time.

The Castellan missiles look interesting but I've got a lot of questions on how they work. The only rules I've found for them are on p. 39 of the SM dex. Hoping to get some help with the following questions:

1. Is there more detailed rules to be found elsewhere for the Castellan missiles?
2. Do models roll to trigger a mine when both entering, moving within and exiting a mine field?
3. Do models roll to trigger when assaulting into, through or out of a mine field?
4. Skimmers and jump infantry are affected normally - does that mean they can fly over but if they end or start movement in a minefield they roll to trigger?



There's a topic over in the DA forum discussing Castellan missiles and they keep claiming the advantage of negating models their cover. This is confusing since if a model stays in cover and doesn't move, how can they ever trigger a mine?

It sounds like I'm missing an FAQ.

At first glance it might be something to look at the rules for minefields in the main rulebook.

That was my first hunch too, but I cannot find that section in 4th ed. Page number?

[This is why I wish you could by the 40k books in searchable pdf format.]

It's in the DA Codex.

Essentially, minefields are leaving the 40K universe.

In their place, napalm missiles.

Capiche?

Ok so part of the confusion is that the DA have a special type of Castellan missiles. But I am not playing DA, I'm playing Ultramarines.

So ignore the question about cover, as that only applies to Castellan Incendiary Missiles.

So I still have the questions:

1. Is there more detailed rules to be found elsewhere for the Castellan missiles?
2. Do models roll to trigger a mine when both entering, moving within and exiting a mine field?
3. Do models roll to trigger when assaulting into, through or out of a mine field?
4. Skimmers and jump infantry are affected normally - does that mean they can fly over but if they end or start movement in a minefield they roll to trigger?
5. Where are the rules for minefields?

Thanks.

See P.205 of the rulebook for Minefields.

Thanks.

Hmm, so that clears up #4 and #5.

The rules as written indicate that you'd have to check for triggering a mine anytime you move in a mine field, whether that me the movement or assault phase.

Correct. Any movement of the model triggers the minefield.

Yup. Whether you moving into, out of, or through, if you're over the minefield expect to lose something. I think question #1 is covered by the rules for minefields, likewise #2 is covered by the rules for minefields stating that each model is hit on a 4+, and #3 is covered by moving, which applies to both moving in the movement phase and moving in the assault phase. Basically don't move into a minefield and try to charge out of it!

This also allows you to perform some fun tactics. For example, you can tank shock enemy troops inside the mine field. Your own units are unaffected by the mines. Since the tank shock forces them to move out of the way they will be hit by the mines.

Why would your own troops be unaffected by the mines?

The rules state that only enemy models trigger mines.

This is another tactic that is commonly used against horde armies. You basicaly just fire the whirlwinds into your own lines and just have you army sit in the mine field. When your enemy wishes to charge you he will take X*Y hits on each unit. where X is the number of minefields in that area and Y is the number of models in the unit. This is one of the tactics that puts a quick end to Ork Assault Hordes and Tyranid Gaunt Hordes.

In one game I watched I saw a unit of 30 guants take some where around 150 S6 hits when trying to charge a unit of terminators.

Except this part of that tactic is illegal - you cannot target your own models.

Only you're not targetting models--you're just laying minefields. Castellans don't require that you nominate a target unit; you just select a point.

Edit: Retracted until I can check the 'dex.

And that is incorrect. See p. 39 of the SM codex - it's very clear on this point.

Yes but there is nothing preventing you from placing them in front of your units and walking on to them.

Of course, but that's not what you said.


Having said that otherwise I got my questions answered - thanks all.

I said within your lines, I did not say on your models. In front of your models still has the option to scatter towards you as well as you to move towards it.
