First up, the one actually being played somewhere!

Malms... oh look out world.

On the plus side: he's probably not going to summon voidsent!

On the minus side: congratulations, you now have a small angry nexus of fiery death pointed at you. Have fun!

Boss fight mechanics: hold on to your butts, healers, cuz there's gonna be fire everywhere

Now, characters in my head but not currently in play anywhere!

Cleave, my Lords of Gossamer & Shadow/ADRPG wandering swordsman: I make it a point to be first in Strength, Warfare, or both anytime I play him

Which means if you come for a straight fight, or anything even remotely resembling a straight fight, you gonna die

Basically, you're gonna want to make an end run on him - magic of some kind or GTFW

GTFO, even
