You fight with a flowing dance, striking in multiple directions at once.
Benefit: Each melee attack you make within 1 round against a different target than the last deals an additional 2d6 damage per previous target hit. For example, if there are three different creatures that you strike, the first successful hit deals no additional damage, the second target hit takes 2d6 extra damage, and the third target hit takes 4d6 extra damage. This damage bonus cannot increase beyond 4d6 damage and is not multiplied on a critical hit. The additional damage is only added once per target on the first attack you hit them with that turn.
