Capital City Entertainers
Entertainers in capital cities are throwing shirts on the ground, which can be looted and worn by players. The entertainers are marked by stars on the map.
Stormwind Entertainer is located in the Dwarven District
Orgrimmar Entertainer is located in the Valley of Honor
These NPCs periodically shoot T-shirts on the ground, which can be looted and worn by any player. These T-Shirts are BoE versions of popular shirts already in-game, such as Golden Filigreed Doublet.
