Bramble Cloak

Spiked protrusions cover your body for the duration.

Whenever a creature within 5 ft. of you hits you with a melee attack, the attacker takes 1d6 piercing damage. If you are grappling a creature while this spell is active, you can choose to deal 1d6 piercing damage to that creature at the start of your turn (no action required).

At Higher Levels. WHen you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for every two levels of spell slot above 1st.
