Pathfinder has that too, so it presumably carried through 3.5e. It’s why wizards don’t wear armor, and only applies to arcane casters, and classes that are meant to wear some armor like bards get exemptions for the tiers of armor they’re meant to wear.

glitchdx@lemmy.world 2 months agodidn’t dnd 2e have you roll a d20 if you cast while wearing armor? too low of a roll and the cast fails? No crit effects, just simple pass/fail, right?

It was a rule in Pathfinder, so presumably it was a rule in 3e.
