Drill Beam

A spiraling beam of pure energy is fired from the tip of the caster's finger after charging for the duration of the casting time. The beam is 150 ft. long and 1 ft. wide and will bore through any nonmagical surface in it's path. A creature takes 10d8 force damage on a failed save, and half as much and a successful one. If a creature rolls a natural 1 on it's save, the creature will be badly injured by the spell and will take 1d20 necrotic damage for 1d10 turns, or until a healing spell is cast on the creature, after the initial damage. The range of this spell maxes out at 150 ft but the caster can choose to shorten the range.

Monks of fourteenth level or higher may spend six months of study to learn this spell, spending 7 Ki points to cast it.
