Hey

When the avenger ability procks , it specificly says that He/she might do any action on the actionbar, even while streesed,

But then we have the Autotrusters , After you preform a action, you may preforme a red boost o barrelroll

so , if avenger is stressed, and a friendly ship goes booom. can he/she preforme a focus, and then a barrelroll, and gain another stress?

No. His ability only grants the one action and the stress override only effects that one action.

Not without Primed Thrusters, at least.

Dang it'd be fun if those were a little cheaper on lower-initiative stuff.
