The Watcher's Eyes (Patreon)

Weapon (scimitar), rare (requires attunement)

It's always better to have more eyes watching your back. You gain a +1 bonus to damage and attack rolls you make with this magic weapon. When you speak the command word, the weapon's eyes glow with a menacing light, providing bright light in a 20-foot radius and dim light for an additional 20 feet that pierces even magical darkness. This weapon has 3 charges and regains all charges daily at dawn.

Such Sights to Show. You can spend a charge to hold this weapon up to the face of a creature within 5 feet of you that can see the light and hypnotize it. The target must succeed on a DC 15 Intelligence saving throw or become affected by your choice of the Command, Charm Person or Dissonant Whispers spell. A creature that cannot normally see (such as a blind creature or a creature with no eyes) is immune to this feature.

Nowhere to Hide. When you cast the Scrying spell you can spend a charge to cause the target to make their save with disadvantage. While you are scrying you can spend a charge to change the type of vision you experience to darkvision, X-ray vision, or seeing the presence of magic as if affected by the Detect Magic spell. While this weapon has at least 1 charge you also become aware if you or a friendly creature within 30 feet of you is being scryed upon and can see any scrying sensor within 30 feet of you.

In all the planes in all the multiverse, there is no place safe from the prying eyes of this blade. Formerly used as a ceremonial tool, this eerie weapon has found itself in the hands of those curious for knowledge beyond their fragile mortal capabilities. Those who come face to face with the multitude of eyes that dot the curved blade often recount little about their experiences, their minds having been numbed by the magnitude of what they have been shown.
