unless absolutely no one comes up with good reasons concerning the above
Druids are restricted to *natural* items only, including stone, wood, cloth, leather etc. but what is the difference between a unnaturally cured hide and a unnaturally extracted and shaped blade?
Stone is not much unlike metal, it even includes metal. ores can be seen as stone or rock, and require a chemical process, just like raw skins to be worked with.
ok, if the innatural about a copper great sword is that chemical process that was required, sure, but leave out the curing etc. as well. And how about Golden Swords? Gold is a metal that does not react with other metals or nonmetals, and is therefor just as natural as wood.
if one finds gold in a river, melts it and shapes it (this proces has 1 unnatural parts) into a weapon, a druid may not use the product. but if someone else has found a cotton plant, harvested it, made thread, wove a cloth and finally made a garment out of it (this proces has 3 unnatural parts), the druid may use the product?
ps stone sickles? glad i'm not playing a druid, because stone isn't really the best material when it comes to cutting branches, herbs etc. (why not gold or silver? =P)
