Lost Souls...

[Ydex]

Magus Crimean Solider applies a huge amount of marks per each battle.

I was using Phantom Ed for sleep, but he ended up quickly chewing through the Silence achievement --2 hits each enemy, removes immunity, and 50% chance to silence--I'm assuming 50% per hit because it always hits every enemy, every round.

APMA passively removes immunity and does Attack Down, Physical Burn, and Permadeath. I put two sets of burning +advantage on him.

Killer Beast does Grievous Burn and Permadeath.
