I remember those characters with Girdles of Giant Strength, Gauntlets of Ogre Power, and Hammers of Thunderbolts, plus Haste and a lot of other nasty items and spells to stack.
I should remember. A character of mine had all these items himself.
I found out the hard way there is an easy solution to such powermongering.
It was known as Mordenkainen's Disjunction.
An Anti-Magic Shell, surrounded by a spherical Wall of Force, also did the job. Disintegrate worked wonders too (a character can be Wished back, but multiple Wishes for the items too? Wizards won't do it.) Or immersion in acid, lava, or a breath weapon under circumstances that made a failed saving throw likely (thus forcing repeated item saves.) Or how about just a fall off a cliff (no amount of strength or number of mighty weapons mitigates the splatter effect of a 1,000 foot fall.) ?
It was almost wondrously ghastly, how quickly a Christmas Tree Character could be stripped of his ornaments, reduced to mundane nakedness, and put in the Dead Book.
