Double Slap

You reach out with quick slaps. Make a melee attack roll, doing 1d4 + MOVE on a hit. After successfully hitting a target, roll a d4. On a result of 3 or 4, you may immediately hit again for an additional 1d4 normal damage. Continue this process until you fail to roll a 3 or 4 on the d4 roll, up to a maximum of four additional hits.

At Higher Levels: The damage dice rolls for this move change to 1d6 at level 5, 1d8 at level 10, and 2d6 at level 17.
