Few questions about this power.
As per errata it effects hordes as a Astartes Heavy Flamer.
Me and my GM cant agree on how that is exactly. He says because Heavy Flamer deal 8+1d5 damage to Hordes, so does Avenger, regardless of Psy Rating. I would read that it is range/4 round up + 1d5, so it is 8+1d5 at PR3, more when PR increases.
Also Heavy Flamer cant be used in melee, can Avenger? That has only come up once, but I'd like official answers to both questions.
). Once its clarified and they understand the rules.
