Slayer is a skill that allows players to kill monsters which are otherwise immune to damage. Slayer experience is awarded upon killing a monster and is similar to its number of Hitpoints. Combat experience is also given at its standard rate, so many
players primarily train Combat by completing Slayer tasks. The skill is an exclusive means for many powerful items to enter the game. Use ::duoslayer-(Player Name) for faster leveling. Upon completing a task you get points that you can spend at the Slayer Prestige shops.
Training
You can begin slayer by talking to the Slayer Task Slave at ::home. Choose the first option; "Yes I would like a slayer task", and that's it, you now have a slayer task. If you'd like a different slayer task, talk to the slayer master, and choose cancel task. Then you can choose to cancel for 100 points or 100T cash.
You can purchase a slayer gem from the shop to keep track of what you need to kill.There is no special method. Get tasks and kill npc's.
You can fast travel to your slayer task by right clicking on slayer master, then choose teleport to task.
