Suggestion - Pulls
I think it’d fit better as a weapon skill (cough greatsword cough) along with an AoE control weapon set.
Adding another gap-closer to a new weapon has been suggested before. Dark Path and Spectral Grasp are the only two available and neither are guaranteed to work because of terrain and big tells that can be dodged.
If spectral grasp and DS #2 would just work better instead..

Corrosive Poison Cloud
Convert it to elite
Inflict a target with a poison cloud, for 15 sec the target has a 240 radius circle following them around affecting up to 3 allies at a time inside the radius every second. Also acts similar to flesh wurm but when you teleport to the enemy it dissipates the cloud.
90 sec cooldown. So even if they cleanse themselves the cloud still follows them around inflicting the conditions on their allies if they get too close.
Haunting Corruption
Corruption. Self vulnerability 5 stacks
Up to 3 targets in the target area are pulled to your location and are blinded for 3 1/4 sec.: hopefully at least one of them won’t block it
