  • Taken directly from the Elder Lumerian

Secondary Variants:

  • Charge a short distance, then stun & knockback anything you hit
  • Also a decent way to move just a little faster

Imp Skills:


  • Take no fall damage
  • The jump is naturally very high, and just 1 jump upgrade inflicts fall-damage
