Skilling
Skilling is the training of a RuneScape player's non-combat-related skills.
For members of PvP-orientated clans, there are a number of reasons to train non-combat skills. Having a higher total/overall level permits access to skill total worlds on PK trips, where there is often increased activity in the Wilderness. Skilling also unlocks quest and achievement diary rewards which benefit PvP: for example, the Wilderness diary allows members to redirect the Wilderness obelisks, and upon completion of Desert Treasure 2 members gain access to the Ring of Shadows (a good and reasonably-cheap ring to use in PvP). Skilling can also serve as a moneymaking method for members to buy PvP equipment, or to unlock other aspects of the game such as PvM.
Training skills with a clan is often more productive and enjoyable than training alone, and the Wilderness Guardians hosts numerous skilling events and competitions to help members level their non-combat skills.
