Eldritch Shield

     You summon a spectral shield made from eldritch runes that protects you from the next damage you take. The next time you take damage, reduce the damage by 1d10 and the spell ends. 
     The spell’s damage reduction increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
