Quickstep Kunai

Weapon (dagger), uncommon (requires attunement)
  This weapon could pass for a simple wooden or bone kunai, but don’t let its crude appearance trick you. Made by tanukin masters, mysterious etchings can be seen on its surface, imbuing it with an ostentatiously visible magical aura.
  Charges. This item has 5 charges, represented by etches on the kunai’s surface. When a charge is used, one symbol magically disappears. Once per long rest you can spend 10 minutes carving 1d4 symbols, restoring that many charges to the blade. If you are proficient with Woodworker’s Tools you restore an additional 2 charges.
  Transposition. When you take the Attack action, you can replace one of the attacks with a special action. You can use this special action to throw the kunai at an unoccupied space you can see within 30 feet. As long as the kunai is within 60 feet of you, you can, as bonus action, expend 1 charge to instantly teleport to the kunai’s location, leaving behind only a puff of smoke and falling leaves.
