Does Impervios still let you roll to avoid dmg from psychic blast?

No

BTW, Impervious does not avoid damage. The roll for Impervious is to determine how much the damage dealt is reduced, either by 2, or to 0.

Since both parts of Imp reduce damage, it has no effect on PB, which states that the damage cannot be reduced.

Hey, I too, have a question about psychic blast. It states that it is a ranged combat action-just like energy explosion, after you move half your speed on a running shot and some other things-I also looked at battle fury. Battle fury in the PAC for the Universe rules says, this character cannot make a ranged combat attack, so does that fall under ranged combat attack/ranged combat action- or just ranged combat? Otherwise while under the effects of battle fury you can still do a running shot energy explosion!

EE is a Ranged Combat Action, in which you perform a ranged combat attack. So, it you have BF and EE on the same click, you cannot use EE.

I assume you ask this question is because of the Doc Ok misprint. Per the Marvel FAQs:

Thanks, I see now, the ranged combat actions require ranged combat attacks hence battle fury covers both.

It was sorta the Doc Ock thing. I just looked at the battle fury reading and it said ranged combat attack-not ranged combat action-like PB or EE.
