100 Tranq Arrows (or Tranquilizer Arrow) are used for rendering creatures unconscious. It does less damage than a Stone Arrow, but increases the target's Torpor. Tranq Arrows can be used as ammo for the Bow, Crossbow and Compound Bow.

Upon hit, they instantly increase the target's torpor by an amount equal to 200% of the weapon damage and give an additional amount of torpor equal to 250% of the weapon damage over the course of the next 4 seconds. (ex. A standard quality Bow would Cause 40 Torpor damage immediately, with a timed release of 50 torpor over 4 seconds.)

They can usually be recovered by walking up to the area of impact, but will be recovered as Stone Arrows, the Narcotic being expended.
