I got this trinket the other day. I like the proc, not amazing but good. I have noticed some issues with it though, it flat out doesn't hit Krosus, similar bosses or mobs will act the same way.
I also noticed if it procs from a ranged ability, it hits under yourself instead of in front of you as if a mob was present. This is why I think it doesn't work on Krosus even if done by normal melee attacks in front of him.
Would it be better to write a ticket or on the battle.net forums ?
Also has anyone noticed any other issues with it ? I know I talked to 2 other people about it and they had the same experience with krosus.
