Crystal Soul Spear

A massive, piercing spear of refined crystal streaks from your hands in a line 60 feet long and 5 feet wide. Each creature in the line must make a Dexterity saving throw. On a failed save, a creature takes 8d6 Force damage and 2d6 Piercing damage. On a successful save, a creature takes half as much damage.

If this damage reduces a creature to 0 hit points, it is disintegrated into a pile of fine crystal dust.

At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the Force damage increases by 1d6 for each slot level above 5th.
