A small fang of a serpent flies from your hand continuously growing until it reaches a point within the range of your spell. Once it reaches its destination it explodes into needle-like shards in a 20-foot-radius sphere centred on that point. Each creature located within the sphere must make a dexterity saving throw. A target takes 8d6 poison damage on a failed saving throw, or half damage on a successful one.

The shards do not necessarily fly in straight lines and ricochet off of non-living materials so damage from the spell can spread around corners easily.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
