Crystal skillchompas are level 97 hunter creatures found north of the Tyras Camp, in the Isafdar forest. They are caught using box traps and give 476 Hunter experience each when caught. Once caught, crystal skillchompas transform into stackable crystal skillchompas, which can be wielded to give benefits while skilling.
Crystal skillchompas can be attacked and explode when killed. If the attacking player is next to the skillchompa when it explodes, they will be pushed back 1 square and dealt 20 life points of ranged damage (this cannot be mitigated by Prayer). Players hunting these skillchompas should take care, as clicking on one will cause the player to attack it. A player can avoid this entirely by equipping a Ranged or Magic weapon without ammunition, or by selecting the "Hidden" option under the NPC Attack Option Settings.
When catching skillchompas, there is a chance of catching multiple in a single trap, up to a maximum of four, with higher levels of Agility giving a better chance. At level 99 agility there is a guaranteed chance of receiving multiple skillchompas from a single trap. With level 99 Agility and Hunter, and no buffs, a player can gain around 700,000 experience an hour. Using an arctic bear, decorated hunter urns and an urn enhancer, the hunter's outfit, enhanced yaktwee stick, legendary tracker aura, and combined catalyst fragment set, a player can gain anywhere from 1,200,000 to 1,300,000 experience an hour. Using the perfect plus potion method and all of the above mentionned, a player can expect over 1,500,000 experience an hour. The legendary tracker aura may be optional, as at level 99 Hunter (with the previous described items/equipments), the success rate of catching Crystal skillchompa is almost 100%.
Crystallise cannot be used on box traps which have caught crystal skillchompas.
