Brindle's Holy Shield

You raise the shield used in the spell’s casting and fill it with divine energy to protect yourself from an attack. You gain a bonus to your AC equal to your spell casting modifier against the triggering attack. If the triggering attack was a melee attack, you also deal 1d8 radiant damage to the attacking creature.

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