Infinity robes are a set of magic armour that are rewards from the Mage Training Arena minigame. Each piece of the robes can be obtained from the Rewards Guardian on the top floor of the arena in exchange for Pizazz points. After Evolution of Combat, Infinity robes require 55 Defence and 50 Magic to wear.
Since they are very hard to obtain and their cost is in the millions, most people use Batwing robes, Mystic armour, Splitbark armour, Skeletal armour, or Lunar armour instead. Because there are several types of armour that provide better stats, but are much cheaper, players generally wear Infinity robes as a sign of wealth, accomplishment, or just for pure cosmetic looks.
The full set can be stored in the magic wardrobe, which is located in the costume room of a player's house.
Official meeting point for the product committal is:
