I tried witchunter's decimating strike with 221% increased culling threshold and palm of the dreamer, and it was fun
The idea here is that if you can get at least 217% increased culling threshold, then decimating strike's minimum 5% damage (which is applied before the cull check) will make any hit instantly kill any normal mob. The palm of the dreamer blows up the culled normals to help kill the magic and rare monsters.
Any normal pack, regardless of how high level or map mods, dies instantly as soon as you hit it even for 1 damage.
Arc with dominus grasp kills everything so fast, so far off screen, the maps feel empty. At least until you run into a rare that didn't die from a palm of the dreamer explosion... I didn't solve single target damage yet. Also didn't work on defenses yet and passive tree is totally messed up from an experiment, build is wip.

Give it a try, palm of the dreamer is relatively cheap for once this league.
