A Trader

Mysterious "traders" have appeared all around the city of Haven (Ocllo on Siege Perilous). You can turn in Blackrock for different rewards. Simply drop the blackrock on the trader and the reward will appear in your backpack. Watch out for player scammers who name themselves "a trader". If a Trade Window opens then you dropped it on an impostor.

Rewards

For each blackrock turned in you can get one of the following rewards.
