Arcane Tattoo

You activate the runic serpent tattoos, shielding you from harm. Until the spell ends, the creature is immune to being Stunned and gains temporary hit points equal to your spellcasting ability modifier at the start of each of its turns. When a creature enters melee range to you, you deal 1d4 poison damage. When the spell ends, the target loses any remaining temporary hit points from this spell and the tattoos return to normal.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can add 1d4 temporary hit points. (Damage stays the same).
