Most unique RAW-legal item used in a game

[Random Bystander]

We all of course have stories of items a GM or player came up with to throw a curveball into play that relied only on Rule 0. However, from daggers which blind or deafen their target to swords which cast Grease on their target, RAW contains plenty of room for offbeat items.

So, what would be the weirdest RAW- or RAI-legal item used in a game, either by you, or which you saw used, which did not come from a rulebook? (Apparatuses of Kwalish, for example, would not count, as they come straight from the rulebook. An Apparatus of Kwalish with continual Greater Invisibility on it, however, would count)

A blatant attempt to stir up idea-fodder.

..Sovereign glue is an extremely versatile DM tool, especially when used by kobolds and goblins.
..Portable holes are a DM's nightmare, especially when used with a potion of water breathing to sink the BBEG's ships.

Always liked the simplicity of glue + caltrops.

Also liked putting the cold and flaming enchantment on a single weapon.

What fan of Captain America hasn't enchanted a shield with Throwing & Retuning?

I have to say, +1 Dagger - Intelligent item (CE), with finger of death (when the dagger felt like it...which was always). The only campaign when we hit Epic, cause the DM constantly rolled 1 for fort saves... .

Curiosity: How do you use a Portable Hole to sink enemy ships? It doesn't leave any hole in the ship's hull, but instead opens into an extradimensional space.

As for the RAW item question: The games that can be played with a simple Hat of disguise... (My group has determined that no character of mine will ever be allowed to own one )

I've seen the Mr. Bearington story. What sort of antics did you get up to?

That depends on which edition you are using. In some, the portable hole is simply a hole that allows passage through things like doors, chests..etc..

I played in a "Monster Game", where players were permitted to play any race at all, other than normal player character races. (Total starting level limited to 3).

The DM allowed for an exception: I was running a Human, but nobody knew it. Thanks to some Bluff skill and a Hat of Disguise (plus the occasional Enlarge Person or Reduce person spell), the other players were convinced that I was running some sort of semi-controlled metamorph. He was an Ogre when they met him. Then he was a Human. Then an Orc. Then a Kobold (thus finishing off my 1st level spells for the day), then a Dark Elf. He was a Stone Giant when it came time for melee combat.

He also used the Hat to alter just his clothing, giving him good camoflauge when scouting. Lots of fun.

I've played every D&D edition since the original (Eldritch Wizardry, Chainmail, and Blackmoor). I don't recall the Portable Hole ever working that way.

Which edition are you referring to?
