Cleave

A slashing attack that adjusts itself to the targets defense and strength level. Roll 2d8 slashing damage, for every spell level you gain add 1d6 to the attack.
Example: Base Cleave does 2d8 whilst a 3rd level Cleave will do 4d8.
From 4th level spell and above Cleave can ignore half of the targets AC, allowing for easier grasping and cleaving.
