Useless Magical Items pt 2

The old thread is auto-saging, so here we go again

Come up with a magical item that is useless, or useful in only extremely unlikely scenarios

Ring of Half Strength - A plain silver ring. Reduces the wearer's physical strength by half. Has no other effects

>Amulet of Recursion

This magical item gives its wearer a +10 bonus to craft checks, but only when attempting to create another Amulet of Recursion.

>Wand of the Chigger

When evoked, the target of this wand must make a DC 10 Will save or else suffer mild but annoying itching for 1d6 hours.

That actually sounds useful. Put that on an strong enemy somehow to render him much weaker. Use to replace rival's ring with, the night before a scheduled swored duel. Used by law enforcement to subdue unruly brutes. Etc.

>Barlow's Bag of Oats

The signature creation of the Archdruid Barlow, who created dozens and distributed them to Druid coves around the world. These items resemble ordinary backpacks, but when filled with dry, nonliving, organic matter, they are able to magically convert their contents into ground raw oats. This item will not function if partially filled, or if it contains any inorganic, living, or undead material.

so it can convert rotten or spoiled food into edible food?

>Falsehood Serum

This potion will cause the drinker to be unable to tell the truth as they know it for six hours after imbibing. They can say non-commital or ambiguous things, as long as it doesn't communicate a truth to any listener.

Tankard of incredible power - Whoever drinks from this tankard believes he is imbued with incredible power.

>Double Axe of Bludgeoning

This magically enchanted double axe does an additional 2d6 bludgeoning damage when the wielder strikes their foe with its flat. Unfortunately, the axe is not designed to be wielded sideways, and the user suffers a -4 penalty to hit when using the weapon as such, and deals a base 1d2 damage with its flat.
