can't understand if this can be better or worst than upped brimstone, in any case it seems like a rework/revamp of brimestone eater; with 3 quanta is a little bit too slow/expensive for being used as an immolation target
It's supposed to be a more offensive yet slightly costly version of brimstone. It also works well with some air spells, as it's airborne (though not mentioned). Heck, you could do some other things with it, including using Death Effect cards, Gravity Pull, Adrenaline, Unstable Gas, and cheap CC like Shockwave or Lightning.
If you think I should lower the cost to 2, I can do that.
