When cast, a boulder is spewed in front of the caster. The boulder travels a short distance before falling to the ground. It explodes upon colliding with an object, dealing moderate physical damage in a small area around the point of impact. Some opponents may also be launched away from the blast radius.
Due to its low requirements and FP cost, Boulder Heave is a very effective pyromancy if used correctly. It can stunlock certain foes and is one of the few ways of reliably hit enemies that are climbing up ladders.
