Blessing of Yinualur

You cause two bony protrusions to magically sprout from your shoulders, which drip with blood and necrotic energy. While you have these bony protrusions, you have a climbing speed equal to twice your walking speed, where you can climb using these protrusions while leaving your hands and feet free. As a bonus action while you have these protrusions, you can make up to two melee spell attacks against creatures within 15 feet of you, dealing 3d10 piercing damage on hit.
