Gauthus says, "Ring of Spears is spell that can dissuade your enemies from approaching too closely, but for those that choose to engage anyways it will provide a regular barrage of targetted attacks. When you so evoke the power of Earth, a ring of sharp spikes, resembling spears wrought of rock, rises from the ground around you. These spears then shift position either when approached, or when the pattern draws on more mana from the caster. In practice, the spell can be cast at pole range to deliver damage as foes advance and retreat, or it can be cast at melee range to continuously provide attacks directed at the foes nearest you. Before you can learn this spell, you must be circle 30. Additionally, you must know one of Tremor or Tremor. It will also cost two spell slots. It cannot be targeted."
