Actual AD&D play from 81-85. It never came up except in the technical sense of multiclassed clerics who used weapons with no problem (and whatever the odd god specific exceptions from the Greyhawk boxed set allowed).So, a different thread about druids and metallic armor in 5e has repeatedly referenced the way Druids were in OD&D / 1e, and how there wasn't really a rule about classes and so on so forth.
Anyway, with the usual caveat of "Everyone played AD&D/OD&D" in a different way, I was looking to do a thread to see how people actually played OD&D and AD&D from 1976 - April 1985.*
So here's the questions to answer, along with my answers, in the following parts:
1. Could Druids wear metallic armor? If they did, what happened?
2. Could Clerics wield edged weapons? If they did, what happened?
3. Could Monks use flaming oil? If they did, what happened?
Nobody tried to violate the class restrictions in the games I was in so the issue of what would happen never needed to be answered.
I fully allowed the cleric/M-U to use daggers in my campaign.
I thought about the restrictions a little and considered them dumb but I mostly played fighters so it did not affect me that much so it was not that big a concern.
