Confused?
If you can stack confusion properly, you might create confusion damage bombs on enemies. You can also receive help from other classes to layer confuse/conditions and ethereal fields are cross-combo confuse. It would be hilarious to see somebody mash '1' and kill themselves with a 1/4 health loss explosion.
