Item: Robotic Hand, wieldable as a weapon; while physically pretty much useless, on a successful hit to a sapient creature, it grabs and removes that creature’s imagination, significantly decreasing their mental stats.

Item: Nissin™ Cup Noodle Ultima Sabre, a +3 hybrid sword/trident that is officially sponsored by the Nissin Corporation; if the wielder makes a statement endorsing or praising Nissin-brand cup noodles while making an attack, the weapon deals an extra d8 piercing damage.

Item: Knifey McKnifeface
The first ever sentient object, Knifey is your friend and will do it’s best to help you in any way possible.

By saying hello to Knifey in Common during a wisdom roll, you get to roll a 20 sided die before hand. On a 19-20 you instantly succeed. On a 13-18 you gain advantage. On a 7-12 it gives you +1 in the roll. On a 1-6 it gives you -2 on the roll and Knifey is silent until you take a long rest.
