The entire set gives a 15% damage bonus while playing Castle Wars, Soul Wars, Fist of Guthix and TzHaar Fight Pit, but does not stack with the Castle Wars armour sets. The Battle-mage robe has very high stats and exceeds even the Torva platebody on average. Torva armour is however better outside selected minigames. It's also easier to get this item, by simply playing the minigame with friends. Despite rumours, this armour is entirely cosmetic outside of the selected PvP minigames. It takes on average 300 wins to receive the 1st piece.
