Buy OSRS Black boater
The black boater is a stylish black hat in Old School RuneScape. It is a members-only item. Any player can wear it because it has no requirements. It gives no attack or defence bonuses, so it is worn for looks, not for combat power.
This hat comes from Treasure Trails. It is a reward from a medium clue casket, where it drops at a rate of 1 in 1,133. That makes it a rare find. Players who want the hat without doing clues can trade for it, since the black boater is tradeable. It can also be noted, and it weighs almost nothing at 0.01 kg.
The black boater has a real use for clue hunters. It is a Master tier emote clue item. Players need it at the STASH spot on the northern wall of Castle Drakan, by the sickle mark on the floor.
The hat can be kept in the treasure chest of the costume room in a player-owned house. This saves bank space. Its examine text says it all: "Stylish!" It is a simple, rare hat that adds a clean look to any outfit.
