What's the most hilariously useless magic item you've ever had in Dungeons and Dragons?

In my last campaign, my players got a hammer that shoots confetti and makes a party blower sound on crits.

A dramatic moment happened where he had to put his pet owl bear down, as it was morphing into a monstrosity because of the big bad evil guy.

Because the creature was on the ground morphing,

he auto-crit. The beast lies there, writhing in pain, trying to hold onto its own self for as

long as possible. You lift your hammer solemnly into the air, feeling the ways of not only the weapon,

but the situation. As you bring it down, you feel flesh give as the skull has been pulverized from

the transformation. The sound of teeth clacks against the ground echoing in the room around

you. The party looks at the ground, and a moment of silence consumes you all.

So I'm doing my second video on Dungeons and Dragons stories in two weeks, don't hate.

And yes, every time the chance to do this comes up, I'm going to leap at it like the hyper-obsessed

nerd that I am.

The plus three sword of Edward Tumbleton slaying.

Edward Tumbledon was a tailor in a nearby city.

They discovered a sword that was very effective at killing him.

Just him. Neither the party nor any other person on the planet had any reason to kill the guy.

The party ended up killing him by blowing up his shop with a fireball. The sword was never used.

Poor Edward Tumbledon, I think at some point he got on the bad side of an artificer who told

him, I have a sword with your name on it, and it turned out to be true. Gave my party a sash of swimming,

see re-textured aquatic cummerbund. They put it on the donkey pulling their wagon and promptly

forgot about it. I haven't, though. Two years later, I haven't.

Ha ha, still waiting on the moment that the donkey will be the only one to survive the flood.
