Cleave

Every creature and object in a 5ft. line within range makes a constitution saving throw, taking 2d8 damage on a failure and half as much damage on a success. If this attack drops the target to 0 hit points, it severs the target along the line of the spell.

Using a Higher-Level Spell Slot. The damage increases by 1d8 and the length of the line increases by 5ft. every spell slot level above first that you use for this spell. If you cast this spell with a 9th-level Spell Slot, the targets do not make a constitution saving throw, and take 10d10 damage, and the attack also severs objects regardless of whether it drops them to 0 hit points or not.
