Soul Prison skill effect is poorly optimized and lags everyone. This isn’t just on low end PCs, I’m on a high end one, and have only been playing LE on low settings due to optimization issues overall with the game.
Suggestion: Lower the frequency or rework the abilities they use completely. Using skills that dont fire so many projectiles or something less flashy will greatly help out.
Also their damage seems bonkers. Not being able to move freely due to lag from their skills is just mind boggling. Please look into severe changes for this mob type
