Like a road flare. It can only be initiated out of combat but it sparkles and makes noise. Just because not everyone has a skill slotted to draw attention. I'm tired of being abandoned while I'm rezzing only to see the word "chest" in the group chat. By the time I reach the group I've walked past the chest and no one wants to go back and show me. I think it would be useful to be able to drop a flare at a chest so everyone can find it. I'll pay crowns.
