You gain proficiency with longswords and begin play with a masterwork steel longsword. If the weapon is lost, abandoned, or destroyed, it reappears in your hand the next time you awake. When you die, your sentience enters the weapon, which gains your mental statistics and skill ranks. The weapon gains a +1 enhancement bonus, +1 for every five HD you have (+2 at 5 HD, +3 at 10 HD, +4 at 15 HD, and +5 at 20 HD). The weapon retains any enchantments which have already been placed upon it. Your weapon-self has normal senses and empathy. You cannot become undead, and you cannot be resurrected except by a True Resurrection, Miracle, or Wish.
