I understand that maybe the constant fear for the necro pants could be to much, but if you are going to nerf it were it only fears at start and end is pretty much useless. You can maybe get a fear out once every 10 times if you time all enemies’ cooldowns.
The pants need some kind of update. Perhaps increase the fear range when you activate and it ends. MAYBE this allows for some usefulness for the essence, otherwise, its just trash.
