Guild Wars 2

Been using this for at least the last 70 lvls of my thief. Another way detonate works is with Signet of Malice. With a good amount of healing stat it will keep you alive longer. Every hit from detonate will return health.

There is a third type of trophy and I think it’s what you are asking about. They have to do with specific events, should be some text telling who wants it. If you already completed the event for the npc the text on the trophy refers to then you can just destroy it.
