This blade was forged for the great thief and assassin Alsheud. The blade is said to consume a small piece of the victims soul, in doing so it becomes a bane towards that target. After a successful Back attack or Sneak attack the blade becomes attuned to that target. Attunment lasts for 12 hrs or until the targets dies. A new attunment can't take place til the first has ended.
Before attunment: +1 hit, 1d4 as a normal dagger. Also against nonattuned targets.
Attuned: against attuned target only, +2 hit, 1d6, 30' Rng.
