The only place to get this item is Komodo Manspecial encounter. Komodo Man has three Komodo pelts in his inventory. These are extremely hard to get as he stands unreachable behind the fence and gets killed very quickly. The only way is to quickly kill the komodo dragon by indirect hit (it can't be aimed behind the fence), non-lethally hit Komodo Man to lure him near the fence, and then steal the pelts. This requires very high Steal skill as the player character has to use it during combat, face to face, and Komodo Man has 10 Perception.
