[Raising hand guiltily]
Game: 1st Edition AD&D
The Adventure: S3 Expedition to the Barrier Peaks
The PC: White Lotus, a "Dual Classed" Ftr/Illusionist/Assassin.
The Party: High level mages, fighters, etc.
The means of destruction: Ring of Spell Storing, with a 21st level Delayed Blast Fireball on it.
What Happened: White Lotus & pals were wandering down a passageway when they were confronted by several of the crashed Starship's Security Robots. We had encountered one before, so we knew they were tough. Since it had been a stationary one, we did NOT know they were fast.
Upon seeing the robots appear in the "T" of the passageway, White Lotus acted quickly- he used the Ring, launching the Fireball with maximum delay so the party could get away from the blast that would be shaped by the enclosed space...
We ran. They caught us. The Delayed Blast Fireball erupted. Several PCs were killed. Some Robots weren't.
The blast survivors mopped up the remaining 'bots, then dragged their charred compatriots home.
Oddly enough, White Lotus wasn't killed by the blast, by his fellow survivors...or by anything else in all the years I've played him.
OTOH, that same party has a high level mage who cunningly put another one of my PCs, a female Paladin named Chandralangra, on the wrong side of a Prismatic Sphere with a ticked-off Pyrohydra, so I guess things balance out over time.
