Slayer

Slayer is a Combat skill that allows players to earn access to unique equipment and combat locations. Slayer experience can be earned by killing monsters in Slayer Areas or through Slayer Tasks. Killing monsters assigned as a Slayer Task also provides Slayer Coins, which can be spent at the Shop to purchase equipment that gives a boost to slayer experience rates or allows the player to access new Slayer Areas.

Some Slayer Areas require the player to wear specific equipment during combat in order to deal damage to monsters within the area (can be bypassed with the Slayer Skillcape), while others have area effects that negatively impact the player while in combat. For more information, see: Slayer Areas.

Slayer Tasks

Slayer Tasks are randomly assigned in the combat page of the game, and are completed by killing the displayed monster. Monsters killed for Slayer Tasks earn Slayer Coins and Slayer experience points equal to 10% of the slain monster's hitpoints.

Tasks are available in five different tiers of increasing difficulty:

Tier	Level	New Task Cost	Extension Cost	Monster Level
Easy	1	Free	100	1 - 49
Normal	25	2,000	800	50 - 99
Hard	50	5,000	2,700	100 - 199
Elite	75	15,000	6,400	200 - 374
Master	85	25,000	12,500	375+

A Slayer Task can be completed by killing the specified number of the assigned task monster, when complete a new task in that same tier will be automatically picked at no cost to the player. Optionally, the current task can be extended before it has been completed (increasing the number of monster kills required for task completion), or a new task of any tier can be chosen. Both extending a task and choosing a new task costs Slayer Coins, the costs for each are listed in the above task tier table.

The number of monsters assigned per task is a random number that generally increases as the task's tier and the player's Slayer level increase. Formulas used to determine both the minimum/maximum possible task size and the increase when extending a task are included within the Slayer Task Mechanics section.

In addition to killing monsters for Slayer Tasks, Slayer experience can be earned by killing monsters found in Slayer Areas, at a rate equal to 5% of the slain monster's hitpoints. If the player's Slayer Task is for a monster from a Slayer Area, the experience rates will stack, giving 15% of the monster's total hitpoints as experience. Slayer experience gained can be increased further by equipping Slayer armour, which can be purchased from the Shop.

Slayer Task Mechanics

The number of monsters assigned per task is defined as [math]\displaystyle{ C_r = \left ( \text{Tier} + 1 \right ) \times 10 + 4 \times \left \lfloor r \times \text{Slayer Level} + 1 \right \rfloor }[/math], and the increase in task size when extending a task can be calculated as [math]\displaystyle{ E = \left( \text{Tier} + 1 \right ) \times \left (10 + \left \lfloor \frac{\text{Slayer Level}}{5} \right \rfloor \right ) }[/math], where:

• [math]\displaystyle{ 0 \le r \lt 1 }[/math] is a random number
• [math]\displaystyle{ \text{Slayer Level} }[/math] is not the virtual skill level, and therefore has a maximum value of 99
• [math]\displaystyle{ \text{Tier} }[/math] is defined as:
  • Easy = 0
  • Normal = 1
  • Hard = 2
  • Elite = 3
  • Master = 4

Therefore, the task size (before extension) is between [math]\displaystyle{ \left ( \text{Tier} + 1 \right ) \times 10 + 4 }[/math] and [math]\displaystyle{ \left ( \text{Tier} + 1 \right ) \times 10 + 4 \times \text{Slayer Level} }[/math] monsters (inclusive).

Auto Slayer

Auto Slayer is an unlock that can be purchsed from the Shop for  150,000. Once unlocked, it adds a checkbox to the Slayer Task panel on the Combat screen labelled "Automatically fight new Slayer Task?" Once purchased, the option can be toggled off and on freely without needing to spend any additional Slayer Coins.

While this option is checked, after killing the final monster in a Slayer Task the player will automatically swap to fighting their next Slayer target. Only monsters in areas the player can currently access can be rolled while auto-slayer is enabled. For example, a player who does not have either a Mirror Shield or a cape such as the Slayer Skillcape that bypasses slayer area requirements equipped would not be assigned Strange Eyed Monsters while auto slaying.

Players looking to take advantage of Auto Slayer should make sure they have gear equipped that will allow them to survive facing all of the monsters in a given category, even after Combat Triangle modifiers to Damage Reduction are taken into account.

Skillcape

The skillcape can be purchased from the store for  1,000,000 after the player reaches Level 99.

Skillcape	Name	Requirements	Effect
	Slayer Skillcape	Level 99	+25% Flat Slayer Area Effect Negation Bypass Slayer Area item requirements for areas that require less than level 100 Slayer +5% Damage To Slayer Tasks
	Superior Slayer Skillcape	Level 120	+35% Flat Slayer Area Effect Negation +8% Damage To Slayer Tasks Bypass All Slayer Area item requirements +10% Slayer Coins

Pet

The Slayer pet has a chance to be unlocked when damage is dealt to a monster on a Slayer Task.

Pet	Name	Effect
	Asura	+20% Slayer Coins

This Section lists all possible tasks for every tier of Slayer.
