Bloody Reprisal

Your blood hardens into beneath your skin.

Until the spell ends:

• Whenever a creature within 10 feet of you deals damage to you, it takes 2d8 piercing damage. 
• At the start of your turn, it you took damage since the end of your last turn, your first successful weapon attack that turn deals an extra 1d8 necrotic damage.
  • Creatures can only take this reactive damage only once per turn.

At Higher Levels: When cast using a 4th-level slot or higher, the reactive damage increases by 1d8 per slot level above 3rd.
