Slams the ground, creating a slow wave of churning terrain that damages enemies in a sequence of areas in front of you. A number of enemies hit by the wave will release a shockwave, damaging other enemies around them. Using the skill again will stop the previous wave. When the wave reaches a target or terrain, it can restart aiming towards an enemy, if one is in range. Requires a Mace, Sceptre, Axe, Staff or Unarmed.
