Eldritch Absorption

Your patron provides you with a means to defend against spell attacks; when a ranged spell attack targets you, you may use your reaction to absorb 1d10, to reduce the damage by the die's total. Any damage absorbed in this way applies additional damage to Eldritch Blast of the triggering attacks damage type, equal to the damage absorbed, applying to one attack roll only, provided you cast Eldritch Blast on your next turn.
