Hello and thanks you for reading this post.
I’ve been trying stuff lately with the skill Wandering Spirits, and since i unlocked the passive node Spectral Putrescence, the game has been a complete mess for me : huge stutters happens when i’m using the skill, my character is not able to move or in a choppy way, which is very bad : i can’t dodge/kite mobs or even move in the game.
I had lag issues with my void knight, because of the number of projectiles and particles that were on screen killed my fps , but i could move, it wasn’t hindering my movements, just dropping my FPS.
If you need any information about my hardware and software, i would be more than pleased to comply 
Best regards and stay safe,
Malestan
