CrimsonMist wrote:I'm definitely on board with having adamantine be as good as mithral - maybe a +1 flat AC bonus and increase the weight and armour check penalty as this allows PCs to dump dexterity more effectively.

Dragonhide could be better than both. Is it possible to change the qualities included with "Material (x)" as the one big flaw with the other material types is that their special qualities are considered enchantments rather than base qualities as mithral does.
