Blood Shield

You create a shield of blood that surrounds you, providing an eerie, pulsating barrier. Upon casting this spell, you take 1d4 necrotic damage as the shield draws power from your life force. Your AC becomes 14 for the duration of the spell, regardless of any armor you are wearing. The shield moves with you, offering its protection against attacks.

The shield is semi-translucent and throbs with a crimson glow, unsettling to those who gaze upon it. While under the effects of this spell, you have disadvantage on Charisma (Persuasion) checks due to the unsettling nature of the shield.

If the spell ends due to your concentration being broken, you take an additional 1d4 necrotic damage as the shield dissipates violently.
