I believe I know the answer, but I'm going to ask anyway. Angela joins the Sniper Grenadiers . Her Frenzy skill allows her to reroll any hits and continue doing damage until she misses, same as Lasers . The Spotter skill allows you to hit on blanks instead of bullseyes. Does this mean that when Angela attacks she will continue rolling damage until she has rolled all bulleyes (misses due to Spotter )?

Yes, spotter affects the secondary damage rolls as well.

Yep.

Yeah, it's kind of ridiculous. But, you have a hero with only 3 health attached to a squad of only 2 figures, so even though they hit hard, they're not that difficult to take out (or at least reduce down to where someone's been killed and the combo no longer works.)

And remember that Frenzy doesn't work against walkers!

I think it's ok. She's by far the most expensive hero and has only 3 health.
