Attractor wands are used during The Great Orb Project minigame. These come in yellow or green, depending on which team is chosen (Wizard Vief's team is yellow, whilst Wizard Acantha's team is green.) The attractor wands are used to pull the energy orbs closer to the altar.
To change teams or to abandon an on-going game, the attractor wand may be destroyed.
- The attractor wands may be used to attract the opposing team's orbs, although this may not work all the time.
