Would there be three seperated dodge attempts for each attack made in the turn?

Shape Change takes place as soon as a target with it is declared.

Super Senses takes place as soon as the target with it is hit and before damage is dealt.

Impervious takes place as soon as the target with it has damage dealt to it.

At least I think I got those right.

So if (from a Special Power) you had a clix (call him Clix B) with all three it would be:

Clix A targets Clix B, roll for Shape Change.
Clix A hits Clix B, roll for Super Senses.
Clix A hits Clix B and deals 3 (anything less than 3 wouldn't trigger IMP as it also reduces damage dealt by 2) damage to it, roll for Impervious.

Looks like it would go Shape Change, for any attack concerning the character.

Entangle, if it was a close combat attack of some type.

Super Senses if the attack hit, but before damage is dealt

And Impervious when damage is dealt

I never remember to ask. I'm sure it's simple- would PB or EW ignore the roll for Impervous? I know you still roll supersenses, but am unsure for Imperv because of when it triggers.

Yes. Even when you roll 5-6 on Impervious you are still reducing the damage to zero. PB and EW deal penetrating damage and penetrating damage can't be reduced.

Thanks for the clearification. I found the bonus penetrating vs impervious to be beneficial as well.

Shape Change and Entangle (and Skrull/DG) occur simultaneously. Between those two, the order is chosen by the active player.

Indeed.

HoT venom + Takedown + Entangle + Vampirism = Fun times?
