Rift

Weapon (rapier), very rare (requires attunement)

This exquisitely crafted and remarkably thin rapier glows with a faint blue light. The magic infused into this item is powerful enough to pierce through dimensions, but requires careful precision to be used properly.

This rapier has a +1 bonus to attack and damage rolls. Additionally, the intense magical energy from this rapier can be focused into it’s tip, allowing the user to pierce holes through reality with single thrusts. As an action, you may choose to spend movement to make a wormhole strike.

When you make a wormhole strike, you may make an attack on a creature within a range of however many feet of movement you spent. Your arm as well as the sword pierce through a small tear in reality and stab the target out of nowhere.

For every 10 feet of movement you spend making a wormhole strike, you can deal an extra 1d8 piercing damage to the target on a hit, to a maximum of 4d8 extra damage.

For all intents and purposes, all attacks with this rapier are still considered melee attacks, and you are considered to be within 5 feet of the opponent while making wormhole attacks, for the purposes of character features that may benefit from this.
