I know it has been ruled in the Warbound thread that you can use Support on someone who is greenlined. Does the same apply to Incap; i.e. can you attempt to Incap fig(s) that already have two action tokens, thereby dealing them 2 damage via Banshee's SP?

Since I am curious to this answer, I would like to know if I am right. So, here is my stab at it.

THE RULE OF ACTION TOKENS
No game effect can result in more than 2 action
tokens on a character. If part of a game effect
would cause this to happen, that part of the game
effect is ignored.

So, since incap would apply another token it can't. But that doesn't necessarily mean you can't use incap. Her next effect would then kick in and deal 2 damage since that character has 2 tokens. That's my take on it.

Yeah but that wouldn't be necessary as you would just need to INCAP a character that has 1 token, and after actions resolve you would deal it 2 damage.

That we get, but times will arise when you can hit those single token characters and another character who may already have two especially in the case of colossals and figs with Indomitable. Keep in mind her base damage is 3 so divvying that up between 3 figs is a lot less efficient than giving each of them 2.

Would an arb care to weigh in?

You CAN Target a character with Incapacitate, after a successful hit you can then place a token on them. If they already have 2 tokens that effect would be ignored, are there any other effects (stunning blow, silver banshee, etc...) Resolves those.

If the effect only mattered about placing tokens rather then how many tokens are on the character it would have been phrased more like Saturn Queens power:

The Rule states a game effect, not an action, is ignored. The action is to use Incapacitate, the effect is to place a token. The placing of a third token would be ignored, but all other effects should continue normally.

As other's have stated; you cant place more than 2 action tokens on any figure. So the max damage from her SP to any one character would be 2.

Right...for a total damage dealt of 6 (2+2+2) against three figs opposed to 3 (1+1+1) distributed to 3 figs. You're dotting my i.

Your forgetting the potential pushing damage she could do.

Don't know if this will work because the use of incap is the cause of another token being placed and if it will be the third token then this effect is ignored that being incap.This is my take on this.

It says that part of the effect is ignored, meaning the part that gives them a token. They were still a Target of the power and still successfully hit.

The problem here is you say that the game effect Incap. will be ignored. Only the PART of a game effect that would cause more than 2 action tokens to be placed on a character is ignored.

Using Incap. as a standard power is a game effect. The rule of actions tokens does not say to ignore the entire game effect.

I am in agreement with Id and Mister Santa. The new rules and the current wording of incapacitate DEMAND this!
