3.5: Use Magic Device
The most comically, hilariously, overpowered skill in 3.5 D&D was a skill that very few classes got, could only be used trained, couldn’t be used reliably and had a drawback if you ever rolled a natural 1. It was also something that wizards didn’t tend to care about having, clerics could almost never take advantage of, and if you had access to it, would take over your build because of what it let you do.
It had a stupid name too.
It was Use Magic Device.
