Power-Up Punch

You strike out with a powerful punch that increases in strength the more you hit. Make a melee attack on a target, dealing 1d6 + MOVE fighting damage on a successful hit against the same creature. For each successful hit, add an additional damage dice, with a maximum number of damage dice equal to double the original amount. The damage resets if you miss or target a different creature.

At Higher Levels: The damage dice roll for this move changes to 2d6 at level 5, 3d6 at level 10, and 4d6 at level 17.
