Having played around a bit, I can say that the volus cloak (instead of melee attack) is extremely good. Anybody got a good idea for a good volus weapon though? Currently I'm using a light shotgun+cloak to get in range, since it's funny and about as effective as what I tried before that. Support class, so it's hard to do any good damage.

Possed Abominations are really nasty, but I think freezing prevents the explosion.
