Cleave

You can make an attack against a for within reach that cleaves into other foes. If you hit, you deal damage normally and can make an additional attack as a bonus action against a foe that is adjacent to the previous foe and also within reach. This cleave attack only counts as one action (and your bonus action). When you cleave, your movement is halved for the current turn. At 5th level, and each additional five levels, you may make an additional attack against another adjacent foe that you also threaten as part of your cleave action.
