I have a new concept for a cursed treasure, similar in vein to chest of rage, sorrow, thousand grogs. I haven't thought of a title, so for now let's call it the...Chest of Thieves!
Basically it's a chest that can be randomly found/dug up from GH quests. By default, it's only worth 800-1000 gold, but every time it is stolen by another crew, it changes color, and DOUBLES in value! It continues doubling for each steal up to five times. It can't be stolen by the same crew twice to prevent players from quickly stacking it up.
I think there could be lots of fun interactions with this, maybe you could sneak it onto another crew's ship to get some extra value out of it! There could be some extra mercenary commendations for selling/stealing different levels of it.
Possible alternative: instead of a cursed chest, maybe it's another Reaper treasure, showing up on the map like the Reaper Chest/Bounty. That would make it easier for pvp encounters to occur, and the chest to gain value.
