I have 30 int so I think i could harden saal from Mithril to octiron - is it worth it? I know I will lose some of the accostimization bonuses, but will the increase in damage offset it?
The actual damage bonus would be minimal. Damage is a function of weight as well as the hardness of the item's material, with various multipliers to both depending on the specific (if I'm recalling my item.dat correctly). Because Octiron weighs considerably less than Mithril, the main benefit of such a hardening would be faster and more accurate attacks. So the short of it is yes, I think that would be worth it.
Though, you'll need a little more than 30 int IIRC...
