Slayer assignment

A Slayer assignment is given by a Slayer master. When you kill the assigned monsters, you get slayer experience, which you wouldn't if it weren't your assignment. This is a list of possible assignments, with the alternative monsters.

Task weighing
Task weighing is the system that slayer masters use to assign slayer assignments. The percentage chance of getting assigned a given slayer task can be calculated using the formula
 * $$\frac{w}{S} \times 100%$$

where $$w$$ is the task's weight and $$S$$ is the sum of all weights for the particular slayer master. Note that the weights of all blocked tasks, as well as tasks toggled off have to be subtracted from the sum $$S$$.

For example, below is a list of monsters that a slayer master can assign:

If a player has level 85 Slayer, and has not unlocked TzHaar and Aviansie tasks via Slayer reward points, then the list will be filtered so that the player can only be assigned abyssal demons, spiritual mages, iron dragons, and steel dragons.

The task weight for these four are 10, 8, 7, and 8 respectively. The pot, therefore, has a total weight of 33, giving the player a 10/33 chance of being assigned abyssal demons, 8/33 chance of being assigned spiritual mages, 7/33 chance of being assigned iron dragons, and an 8/33 of being assigned steel dragons.

Assuming all tasks are available and this is not outdated/incorrect, the total sum of weights are:


 * Krystilia: 204
 * Turael: 172
 * Mazchna: 216
 * Vannaka: 389
 * Chaeldar: 407
 * Nieve/Steve: 236
 * Duradel: 271
