Sleep Arrows

The purple Tseramed Arrows are specifically made by the Ranger Tseramed. Besides a modest increase in damage, the tip is made from the stingers of Giant Bees, giving the arrow the ability to put the target to sleep. Despite this useful effect however, they are rare, since as said, only Tseramed makes them.

Tsermed gave the Avatar some for free in Ultima VII.
