James McMurray said:Of course, that +5 sword is going to have a hardness of 15 and 35 hitpoints. Add adamantium to it and you've got 25 hardness and 45 hitpoints.
I think the lesson here it to spend the extra couple grand for adamantium if you plan on making a powerful weapon. And put that weapon away if a big critter takes a swipe at it and manages to nick it.
