As Lancelot, hit 3 enemy gods while charging during a single use of The Grand Joust.

Relatively straightforward. The Grand Joust is Lancelot’s ultimate ability. When used, you mount your horse and charge forward. You get some wiggle room, as you can control your horse in this area, so the enemy gods don't have to be in a straight line. Simply hit 3 enemy gods in a single use of this ability.

Best attempted in Arena as enemy gods bunch up a lot, or Joust as you only need 3 gods, but really any Game mode could work when it gets to the stage of them grouping up.
