Cone of Protection

You project a 20 foot cone in front of you, emerging from your palm or spell focus. Any ranged weapon attack or spell attack that passes through the cone has its damage reduced by 2d8. As a bonus action you may change the direction of the cone or you may turn it off without losing concentration on the spell. You may then use a bonus action to bring the cone back in whatever direction you choose on any subsequent turns.

Using a Higher-Level Spell Slot. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
