I have two questions that came up in a tournament game today, that I wanted to get the realms opinion on

1st:
Hand Ninja making his free action attack against Loki, who rolled shape change. The question came from whether the hand ninja couldn't make that attack, and not attack Loki again for the rest of the turn, or whether he couldn't make the attack, but still use a close combat attack. We discussed this a little and the judge wasn't partial to either a yes or a no, so we simply rolled off.
I'm pretty much for it being able to make the second attack (even though it was my Loki ) because the shape change text simply states that they must choose a different non-free action.

2nd:
Sharpshooter vs character behind stealth. Here's the setup:

XXXXOXX
XXXHHHH
XXXHYHH
XXXHHHH
XXXXXXX
XXXXZXX

O = target. Y = character standing on hindering terrain, that possesses stealth. Z = Sharpshooter. H = hindering. X = clear.

Can character Z make an attack on character O? Judge ruled it as a no because the line of fire went through the square occupying character Y, who has line of fire drawn to them blocked. I was under the impression stealth only worked if the character was specifically targeted. Did I miss something?

Thanks in advance!

The rule is that if the Shape Change roll makes your intended action illegal, you must give the attacker a different action of the same type (free/non-free) - so if the figure was attacking through a non-free action (say a close combat action) it could be given another non-free action instead (say a move action).
However, the Hand Ninja's From the Shadows attack is a free action, so you need to give the Ninja another free action instead.
It depends. Sharpshooters can ignore opposing figures when drawing line of fire, but not friendly figures. So if Y is on O's team Z can fire away. If Y is on Z's team the line of fire from Z to O is blocked.
You are right though that Stealth is only relevant when drawing line of fire to the Stealthed figure itself.

1) Shape Change makes it so no attack can be made against the character by the attacker for the rest of the turn. If I'm not mistaken of course.

2) You ignore opposing characters for line of fire when using sharpshooter. Meaning, you act like he isn't there. The guy you're targeting will get the +1 from hindering but, he can still be shot at.

Edit: NINJA'D, good reflexes Quebbster

You're not mistaken.

Okay. Thanks guys!

Guess we made both rulings wrong during the game

Would this mean that if a Hand Ninja obtained perplex or outwit from Oracle, it must use it?

That would be a free action, yes.

Well, I like to think of judge's rulings in the middle of games like this --

The source material, comic books, make no real effort at maintaining a logical set of rules for character interaction... so when you get a ruling in the middle of the tournament which was later proven wrong, that is just the comic-book-ness of the game coming through.

Eh, the guy rolled 3 crit misses in a row on me. I think he deserved his second attack on Loki that turn with hand ninja

Perhaps Bendis was writing that book and figured the three crit misses in a row -- and then the ruling that he couldn't attack again -- would increase the angst for the character and also help to throw away ten years of continuity in the next issue.
