and jar of spiders. When you have horrify readied you can let a bunch of enemies get close so you can get all 5 for soul harvest. Then you horrify them all away from you. Unbreakable grasp + jar of spiders and soul harvest at 5 is pretty deadly. And with jar of spiders you can be simultaneously injuring every single enemy on the screen. Plus they are good for kiting (which you have to do a lot of cause they really are weak, even with the soul harvest buff). You can throw them at your own feet as you are running away.

If you are wearing equipment you can just wander in, cast soul harvest (or not, really doesn't matter) and kill everything fast enough that recovery is just one health globe away.
