Myriad (Patreon)

Weapon (shortsword), very rare (requires attunement)

The remains of an ornate mirror forged into a shattered blade. In each shard of glass, one sees their own reflection, but with slight differences in features or expressions only a discerning eye would notice. You gain a +2 bonus to attack and damage rolls you make with this magic weapon.

Reflection Group. While holding this sword you can cast the Mirror Image spell without expending a spell slot. Once you use this property it can't be used again until you finish a long rest.

Superior Fractal. When a creature within 5 feet of you targets you with a melee attack, you can use your reaction to make an attack against the creature with this weapon. You make this attack immediately before the target makes its attack roll. If the Mirror Image spell is active when you use this property, this attack deals an additional 1d4 piercing damage per illusory duplicate. If your attack hits, the target makes their attack roll with disadvantage.

One-Way. As a bonus action you can enter a polished surface you are reflected on, even if the surface is smaller than your body. When you do so, you enter a pocket dimension within the polished surface that is an illusory reflection of the space outside. While in this dimension your physical form is visible to creatures that observe the surface and you can see what occurs outside of the dimension, but you cannot hear things outside of it. You can exit the pocket dimension as a bonus action, appearing in a spot of your choice within 5 feet of the polished surface. If the surface is shattered while you are in the pocket dimension you take 4d6 slashing damage and 4d6 force damage and reappear within 5 feet of the broken surface.

A simple mirror does not demand attention or notice, common enough as it is in the world. But for those curious enough to peer closer at their reflected doppelganger they may sometimes notice an errant twitch, a blink a hair too quick or slow, a curious smirk tugging at the corner of the lips. Those that learn to harness the mysteries of the many refractions they perceive find themselves confounding their opponents through duplicity and imitation brought to life.
