Hmm. I suppose solid mithral would weigh about five times as much as wood for the same volume, calculating it out. Which is definitely not intended. However, hollow mithral might work (although it is of course harder to make, but who cares? ) I'll probably add a note to that effect.
Well, don't I just feel silly.Also, speaking of ends, is that enchantment on just one end or both, as quarterstaves are double weapons by default and it seems like it's one end but I'm not entirely sure if that's the case or not.
However, that gives me an idea to make one head Defending... hmm. How about that?
