The Charlatan - Reward

[oishi]

Seekers of Adoulin Missions - The Charlatan is there anyway we could trade in for a different neck I know you could trade the ring that you get from the end of SoA mission why not the neck piece?

At this time, (and I even remember reading this somewhere), there is no option to trade in and get a different neck piece once you've chosen and received one.

There is no way to exchange currently, but the devs are actively working on it right now.. They are stuck on trying to figure out how to do so w/o breaking existing npcs so might add a new npc to handle it.
