The one item I can't forget: the Oculus of Abaddon

Written for the October 2026 RPG Blog Carnival, theme: Magic Items, the Weirdest and Best.

The flashy swords don't stay with me. Neither do the +1s. What stays is a small crystal sphere with a red pinprick of light inside, warm to the touch, and the fact that holding it makes you want to put it in your own eye socket.

It's the Oculus of Abaddon, an artifact from the Kingmaker adventure path, and it's the best magic item I've ever read because its curse isn't a stat penalty. It's a want.

What it does, plainly

While held, it fills the holder with a sudden desire to pluck out an eye and seat the oculus in the socket. Doing so costs 1d8 damage, 1 point of bleed, and 2 points of Constitution damage. Once seated, it can only come out by ripping it free, for the same cost again. Seated in an empty socket, it immediately heals the damage you did getting it in.

What you get for the eye:

• Darkvision 120 ft. (constant)
• True seeing once per day, as a free action
• Greater scrying three times per day
• Planar binding once per week, only to summon natives of Abaddon (daemons, soul eaters)
• See and hear through your familiar at any distance, as long as you share a plane

The oculus of Abaddon's greatest power, though, is its haunting beckon. This ability is usable once per year, and allows the user to manipulate the minds of a huge number of targets, provided that the end goal of the manipulation is a tragic or otherwise horrific fate for those being manipulated.

That's mass charm monster at a range of one mile, with a telepathic link to every mind in the area. Creatures of 6+ HD get a DC 22 Will save. Spell resistance applies.

Why it's the weirdest one I know

Three things, and they stack.

The cost is paid in flesh you can't see. Pluck the eye, take the damage, seat the crystal, and if the socket was already empty it heals you clean. The item erases the evidence of what you gave for it. That's a curse written as a kindness. A player who starts with one eye is immune to the damage and still fully subject to the want.

It will not work for anyone good. The oculus is neutral evil, with a limited and hateful intellect of its own. It refuses to activate its powers for any user who isn't neutral evil. So the item doesn't just tempt the wicked. It converts the curious. A neutral character who wants the true seeing and the scrying has to slide toward evil to get it, and the slide is the price. There is no mechanical gate that says "must be evil." The gate is in the item's judgment, which is a much more interesting thing to hand a table.

Its big power only fires toward atrocity. Once a year, you can rewrite the minds of everyone within a mile, but only if the ending you're steering them toward is tragic or horrific. You don't get to use it for a rescue. The item's grandest ability is unusable for anything you'd want to be seen doing.

The line that makes it a DM's dream

How do you destroy it? Not with a grand quest. A DC 30 Knowledge (arcana) check tells you the method:

To destroy an oculus of Abaddon, it must be smashed by a bludgeoning holy weapon wielded by a permanently blinded humanoid. Alternatively, any bludgeoning weapon wielded by a permanently blinded good outsider with at least 7 HD will work as well.

Sit with that. The counter to an object that costs you your sight is someone who has already given theirs up, permanently, and is still good. In Golarion the obvious answer is Vildeis, the empyreal lord who tore out her own eyes on emerging from Heaven and has never taken them back. The cure is a person, not a spell.

If I ran it

I wouldn't put it in a chest. I'd put it where the party can hear it described, and then I'd let a player decide. No save against the want while it's in hand, because the want isn't magic acting on you, it's the item being honest about what it is. And I'd make them find the blinded good outsider themselves. The session where the table realizes the only clean way out is to go find someone who already paid the price is the whole reason to use the item.
