Crimson Shield

You quickly draw blood from your palm and form it into a momentary shield of hardened crimson energy. The target gains resistance to one damage type of your choice until the start of your next turn.

     If you cast this spell on yourself, you may instead choose to gain temporary hit points equal to 1d8 + your spellcasting ability modifier.

     Blood Sacrifice. When casting this spell, you take 1d4 damage as your blood manifests as protective energy.

     At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the temporary hit points increase by 1d8 for each slot level above 1st.
