Item: Ring of Pee Pee Death; according to spells like Identify or similar magic-reading, it allows the wearer to cast a spell called “Pee Pee Death” at will. No one seems to have heard of the spell before, and as such are unsure exactly what it does, but I doubt you’re going to find anyone willing to be a test subject.
Item: the fORB; shows more intelligence and independence than most orbs, communicating mostly through near-gibberish. Those with more experience with normal Furbies might be able to give more detail as to its behavior, but my first thought was the surrealism of the Pantry app, which grants the ability to transform objects: it can clean skeletons, carve carrots into totems of itself, and produce keys by consuming clothing.
Item: skub. Opinions run high about skub, so be careful–upon the tub being opened, each character on the field flips d2 to either attack or defend it, abandoning all other goals until the opener (who retains their will) closes it.
