Razor-backed kebbits are Hunter creatures found in the eastern part of the Piscatoris Hunter area, just west of the Falcon area. Catching razor-backed kebbits requires a Hunter level of 49 and a noose wand, giving 470 experience per kebbit. They drop long kebbit spikes for kebbit bolts, used with a Hunters' crossbow. Unlike other kebbits, they do not drop fur for camouflage clothing. A quick way to reach them is to teleport to the Phoenix Lair and head east, or use the fairy ring AKQ.
In order to catch these creatures, you must search the 3 burrows, follow the tracks while searching and inspecting the plants and bushes.
