From publisher blurb:
Add a little flair to your arms and armor and ReArm Yourself!
Along with a few additional weapons and armor for your Swords & Wizardry campaign, ReArm Yourself! includes options for making weapons and armor just a little more unique. Is that sword Dwarf-crafted or is it just for show? What exactly is that 'leather' armor really made of? And how is all of that fancy plate armor of yours actually decorated?
ReArm Yourself! also includes a couple of new tricks for your Wizard: Magical Gems allow items to be enhanced with minor magics, or if your opponent is getting you down with his own Magical Gems, the new spell, "Destroy Gem", can help out.
