That's the problem with that stereotype. I won't wear metal but I'll use metal weapons. Oh I will wear metal jewelry. I'll use metal tools. But we're a metal or no For the Love of nature no don't worry metal armor. Are you trying to hand me a metal metal half plate no no no it's not made of metal is actually made from the hide of a bulette Ohhh OK sure.
But that's a great thing, now the druid works together with the ranger for their leatherworker's tools proficiency and the dwarf for their blacksmithing proficiency to create a medium armor made from an exotic creature. It's an easy hook for the dm and it provides more bonding in the group.
Not to mention it's awesome to wear the hide of a weird creature.
