For clarity, nowhere does it say (to my knowledge) that druid don’t like metal, or are allergic to it. Only that they will not wear armor (and shields) made of metal.
they are perfectly happy fighting with their steel scimitar, sporting their silver pendant, and use their golden sickle. But some reasons that are stated but not explained, the will not wear armor made of it. They won’t combust if they sit on the iron throne (unless they cast heat metal on it beforehand) and may still enter the gate even if they have to push an forged iron.
i believe the idea is that plate armor is a symbol of «modern» and «technologically advanced» civilisation, and Gygax imagined the druid as a symbol of an ancient, perhaps even antiquated civilisation. Unlike the cleric that was a chassis for priests of different religions, the druid IS a religion with it’s own philosophy and, apparently, taboos.
So, part of the problem is that Gygax ... didn't create the Druid, Dennis "Bunnies & Burrows" Sustare did. And there is very little that he has said about it- one of the few sources I have found that is informative is this interview he did with the
Grognardia website:
You're specifically thanked in the credits of Supplement III to OD&D, where you're called "the Great Druid." There's also a druid spell in AD&D called "Chariot of Sustarre," which was named in your honor. What role, if any, did you have in the creation and/or development of the druid class?
When the thief class was released in the Greyhawk supplement, as an addition to the original fighter, cleric and magic-user, we became interested in other possible classes beyond these four. I wrote up and mimeographed a set of rules for a new druid class, for our internal play. After some playtesting in our game, I revised it with a new mimeograph rule set, still just for our own use. But when we went to early GenCons, a copy got into Gary's hands, and thanks to some advocacy by Tim Kask, they revised the rules once more and published them in the Eldritch Wizardry supplement. Tim added the Chariot spell at the time (it was not one of my original spells, and the misspelling of my name was deliberate). I consider this my first published game design, although Bunnies & Burrows was released the same year (1976).
What were your inspirations in creating the druid class?
...I was familiar with druids from literature about early England, especially during Roman times. The most immediate inspiration, of course, was their mention as a monster in Greyhawk (but not as a character class). Initially, I was trying to make them related totally to plants and animals, but felt they needed a little more firepower (literally).
Another great source is Dragon 12 (February 1978), which has a great historical article called
The Druids. If you look through it, you'll probably see all sorts of antecedents for Druid rules, like Pliny the Elder's discussion of mistletoe.
The one thing you don't find, and I've never found, is a discussion of the basis for the armor rule. Here's the original wording:
Druids are able to employ the following sorts of weapons: Daggers, sickle or crescent-shaped swords, spears, slings, and oil. They may wear armor of leather, and use wooden shields. They may not use metallic armor.
Eldritch Wizardry p. 2
So where did it come from? Got me. Best guess is a combination of two things-
First, the general wilderness vibe.
Second, and just as important, Sustare does say that he was looking at the new Thief class when he made the druid. The new Thief, of course, also had the same armor limitation.
@Faolyn - Great find! Thanks. There is always more stuff out there; that said, I limited it to 1986 for a reason; in the interregnum after UA and before 2e, there was some strange expansions to the rules and the classes as the superstructure of OD&D/1e was groaning and falling apart (IMO). Still, I can't think of any other clear references like that.* Awesome!
*DMG, p. 43, states that "Elfin" chain mail is not subject to heat metal because it's ... not ferrous based? So it's not metal, maybe? At some point ... I can't even.
