While you are working on this, can you please work in proper support for armor material types (mithral, adamantine, etc). Some new bonuses are needed (e.g. adamantine dr is useless), and typing needs to be fixed (e.g. mithral full plate should gain PRR/MRR as if it were heavy armor, not medium). This is still very important to do, along with adding these material types to random loot-gen items, as druids still cannot wear any random loot-gen medium armor (it's all metal).
Please, please. It's been at least two years since material types were busted.
