The red cavalier is a piece of headwear. There are no requirements for wearing this cavalier, and they do not confer combat bonuses upon the player.
To obtain a cavalier, a player can either trade with another player or receive one as a Level 3 Treasure Trail reward. The red cavalier can be stored in the Treasure chest, which can be built in the Costume room of a player-owned house.
