In an attempt to provide proper flavor and opportunities for amazing story, I will be incorporating the following rule in the Dark Sun game;
Choose a single weapon your character is proficient in, you can know quickly cobble together improvised versions of that weapon. The improvised weapon functions in every way as the actual weapon, including allowing you to use all appropriate feats and abilities with it.
This is to go along with the Dark Sun Weapons Breakage Rule and Innate Enhancements;
Innate Enhancements: All characters gain an innate Enhancement Bonus to Attack, Damage, and Defenses based upon their level.
Attack and Damage: +1 at 2nd, 7th, 12th, 17th, 22nd, 27th
Defenses: +1 at 4th, 9th, 14th, 19th, 24th, and 29th
Weapon Breakage: On a roll of a Natural 1 your weapon breaks. You may choose to reroll your To Hit or Damage roll once at the expense of your weapon breaking.
