Came across this one and added it to the list in the first/initial post at the top of the thread:

(don't do the next quest nor throw this away)

Very unique and helpful in some situations (lots of good ideas in the comments)...

Not really dicussed in the comments but it could be used like a 'Skull of Impending Doom' to auto-break CC though once you get into combat you can't un-equip it due to it being a trinket... I could MAYBE see it being used by a druid flag carrier jumping off the roof to cap a flag to auto-clear any CC every second (but even then it could work against you if they grabbed the flag so not sure...).
