A touch from the weapon, which glows with blue energy, disrupts the life force of living creatures. Each touch channels negative energy that deals 1d6 points of damage and possibly also 1 point of temporary Strength damage. (DC 11 Fortitude saving throw negates this damage.)
The weapon has a special effect on undead creatures. Undead
struck by the weapon suffer no damage or Strength loss, but
they must make successful Will saving throws (DC 11 Will) or flee as if panicked for 1d4 +1 rounds.
