Tusk

Through some mysterious power, you gained the ability to harness the natural rotational energy of the golden ratio.

Act 1

Your fingernails spin like buzz saws, you can fire them like bullets dealing force damage equal to your martial arts die + DEX.

Act 2

You have learned to apply the golden ratio. When you miss with a nail bullet, you may expend 2 ki points to create a tracking vortex with a movement speed of 10 feet. This vortex tracks the initial target for 1 minute or until you dismiss it as a bonus action. The target may make a DC 15 dexterity saving throw to dodge the vortex, on a success, the target takes no damage and the wormhole disappears, on a failure, the target takes damage equal to their armor class.

Act 3

You may expend 4 ki points as an action to imbue yourself with the spin, creating a vortex that you can enter. For one minute, you may teleport 30 feet to an unoccupied space that you can see as a bonus action.

Act 4

When you hit a creature that has 100 hit points or less, you may expend 7 ki points as a bonus action to cause them to spin infinitely. The target takes damage equal to your martial arts die + WIS at the end of their turn until they drop to 0 hit points or you dismiss the infinite rotation as a bonus action.
