These exceptionally well crafted arrows bear a powerful enchantment. If the first target they strike is slain, they will overpenetrate and will attack another nearby target. This carries on until it misses, or there are no targets in short range. Each link drops the accuracy of the arrow by 25%. The additional targets are selected at random so firing into mixed melee is inadvisable.
This arrow helps skilled archers to kill multiple weak foes, though as it provides no additional damage, is of limited use against powerful opponents.
Once the arrow misses, all enchantment is lost.
