Crimson Serpent

A burning snake composed of fire streaks toward a target within range and bursts in a wash of flames. The target takes 2d6 Fire damage and must make either a Strength or Constitution Saving Throw of the caster’s choice versus the caster's Spell Attack Modifier. On a fail, the target takes full damage and is knocked prone in an adjacent (5 foot) space opposite the direction the Crimson Serpent spell was fired from. If no space is available, the target is knocked prone. On a successful save, the target takes half as much damage, and is not knocked prone.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
