So I just got Tirathon's Betrayal and I was just checking to make sure it was better than my other trinket (I'm 99% sure it is), but when I ran it through Simcraft it was a DPS loss, and I noticed that the on use isn't doing any damage, so it's safe to imagine Simcraft isn't activating it. I imagine I'd use it with every Vendetta, but I don't really know how to make Simcraft do that.

I thought that if I just added
Code:
actions+=/use_item,name=tirathon's_betrayal,if=debuff.vendetta.up
it would do it, but then when I sim with that it gives me the error "Player attempting 'use_item' action with item 'tirathon's_betrayal' which is not currently equipped." even though it's what I have equipped, and the ID matches the Wowhead ID.

So I'm kind of confused, I looked through all the options but don't see anything about on use trinkets, tried googling but couldn't find anything there either. Not really sure what else to try, and I realize it's not a huge deal since there aren't too many on use trinkets, but I was just curious if it was an easy fix.

Thanks in advance.
