A Large XP lamp (Agility) is a rare prize from Treasure Hunter. Rubbing the lamp grants the player a definite amount of Agility experience scaled to their Agility level, after a confirmation. Freezing the Agility category on Treasure Hunter will remove these lamps from the list of possible rewards. These lamps cannot be banked.
