Hellhounds

[buzzkill]

Sounds good. I think I might take Timo's correction and create Greater Hellhounds that breathe plasma!

How about hellfire as a breathable element, for deep demonic breathers. Something like FIRE + MANA, maybe a little CHAOS or ACID thrown in for good measure.

Fire + Darkness, per balrogs. Have it destroy items on the floor too, perhaps?

Edit: or you could just rename Plasma to the more thematic Hellfire.
