Bloody Thicket

You hold your focus up to your chest, drawing blood from your body and causing blood-red thorns to surround you in a 10-foot radius. You then take 1d6 necrotic damage, this damage cannot be reduced in any way. Each creature in the affected area other than you must make a Dexterity saving throw. On a failed save, a creature takes 3d8 piercing damage, and on a success a creature takes half damage.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage the caster takes increases by 1d6 and the damage creatures take increases by 1d8 for each level above 2nd
