The trickster robe legs are part of the trickster armour set. They require 85 Magic, Defence, and Ranged to wear, but not to obtain. They may be received after winning a game of Soul Wars - an interface will appear from which one of the three hybrid armour legs can be chosen. The chance of receiving the legs is increased if more games are won, and they can only be received if there is space in your inventory. It can also be bought from Stanley Limelight for 700 thaler. The legs normally give no bonuses and are cosmetic, but in Castle Wars, Soul Wars, Fist of Guthix and TzHaar Fight Pit, they do. The entire set gives a 15% damage bonus while playing those minigames, but it does not stack with the Castle Wars armour sets.
