Claymore

You place an area denial explosive spell anywhere within 5 feet of you. Choose a 10 or 20 foot cone originating from the chosen point to be the area of effect. When a creature other than you enters the area of effect or starts their turn inside the area, the explosive goes off. All creatures in the area must make a Dexterity saving throw. If the 20 foot cone was chosen this roll will be rolled with advantage.

On a failed saving throw, take 1d10 thunder damage and 2d10 piercing damage, as explosive force and ball bearings fly through the air. On a successful save take half damage.
