Slayer is a Combat skill. Unlike other Combat skills, Slayer does not directly impact the player's combat abilities. Instead, players are tasked to hunt down specific monsters in exchange for unique equipment and combat areas that are critical to game progression.

Slayer Areas

- Main article: Slayer Areas

Slayer is a special   Combat skill that only interacts with specific combat areas known as Slayer Areas. Each of these areas requires a minimum   Slayer level to access, and some also require the completion of a specific Dungeon. Some Slayer Areas require equipping a specific item purchased with   Slayer Coins; the player can access the area without this item equipped, but will not be able to deal damage to any of its monsters. Unlike normal Combat Areas and Dungeons, Slayer Areas may also have an "Area Effect" that empowers its monsters or weakens the player.

Monsters in Slayer Areas often drop useful equipment, as well as items needed to unlock other Slayer Areas or Dungeons. Making one's way through increasingly difficult Slayer Areas and Dungeons is the cornerstone of Melvor Idle's Combat progression.

Slayer XP and Slayer Coins

  Slayer experience is earned by killing the specific monster assigned by the player's current Slayer Task. Killing "off-task" monsters in any Slayer Area will also reward Slayer XP, but at a much lower rate. Unlike other Combat skills, Slayer XP is rewarded only when a monster is slain, not per player attack.

The amount of Slayer XP earned is based on the slain monster's total   Hitpoints (HP). Killing a Slayer Task target in any area awards Slayer XP equal to 10% of the monster's max HP. Killing any monster in a Slayer Area awards Slayer XP equal to 5% of the monster's max HP. These sources are additive; for example, if the current Slayer Task target resides in a Slayer Area (as most do outside of the early game), killing it will award 15% of its max HP as Slayer XP.

  Slayer Coins (SC) are a special currency awarded by killing Slayer Task monsters. These coins can be spent at the Shop to purchase and upgrade special   Slayer equipment, gain access to new Slayer Areas, buy resupply packs of various consumable items, and more. Like Slayer XP, Slayer Coin acquisition scales with a monster's max HP. However, Slayer Coins can only be obtained from Slayer Task monsters; "off-task" monsters in a Slayer Area will not drop any Slayer Coins.

This table lists the XP and   Slayer Coins earned (before any other modifiers) under various scenarios:

Fighting Slayer Task In Slayer Area   XP   SC
(% of Monster   HP)
Yes Yes 15% 10%
Yes No 10% 10%
No Yes 5% 0%

Large amounts of   Slayer Coins are also rewarded by completing certain   Township tasks.

Generally, the most efficient way to farm   Slayer Coins is to enable   Auto Slayer and idle the highest survivable difficulty tier with gear optimized for damage output. The Combat Simulator can be used to find the ideal Slayer Task tier and equipment loadout for maximum Slayer Coins.

Slayer Tasks

The player's active Slayer Task can be viewed in the "Slayer Task" panel of the Combat UI, and is completed by killing a certain number of the the specified monster. Monsters killed for Slayer Tasks award Slayer XP and   Slayer Coins equal to 10% of the slain monster's maximum   Hitpoints (HP).

Slayer Task Tiers

The monster requested is randomly chosen based on the tier of the selected Slayer Task. Slayer Tasks are available in seven different tiers of increasing difficulty, each with a minimum   Slayer level requirement:

A new character's initial Slayer Task will be selected from the Easy tier.

Receiving New Slayer Tasks

When the active Slayer Task is completed by killing the specified number of the target monster, a new task from the same difficulty tier will automatically start at no cost to the player. If a different task is desired, clicking "New Task" allows for the selection of a task from any available tier at the cost of   Slayer Coins. The current Slayer Task can also be extended before it has been completed, increasing the number of monster kills required for task completion, for half as many   Slayer Coins as a new task of the current tier.

When choosing a new task, a monster of the selected tier will be chosen at random. Potential monsters from Slayer Areas will only be chosen if the player meets the area's minimum   Slayer level, has completed any one-time unlock requirements, and owns (or has previously owned) any equipment required for entry. (Access to gear that bypasses Slayer Area item requirements, such as the   Slayer Skillcape, will also qualify for this check.) For example, if a player had previously purchased   Climbing Boots but has since sold them, it is still possible for that player to receive   Perilous Peaks monsters as a Slayer Task. These rules are relaxed when a task is automatically assigned (following the previous task's completion) while   Auto Slayer is enabled; when this happens, the player will only be assigned monsters from areas that can be accessed with their active equipment set.

Slayer Task Duration

The number of monsters assigned per task is random, but generally increases with the player's   Slayer level and with higher difficulty tiers. Specifically, the number of monsters required for a new 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 duration 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 the true (not virtual) skill level, and therefore has a maximum value of 99 (  120)
  • [math]\displaystyle{ \text{Tier} }[/math] is defined as:
    • Easy = 0
    • Normal = 1
    • Hard = 2
    • Elite = 3
    • Master = 4
    • Legendary = 5
    • Mythical = 6

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 upgrade that can be purchased 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, the player will automatically receive a new Slayer target from the same tier after killing the final monster in their current Slayer Task. Only monsters in areas the player can currently access can be rolled while Auto Slayer is enabled. For example, a player who has not equipped the   Mirror Shield (or an item that bypasses Slayer Area requirements like the   Slayer Skillcape) would not be automatically assigned   Strange Eyed Monsters, even if they have an unequipped   Mirror Shield in their Bank.

Players intending to idle with Auto Slayer should make sure they can survive encounters with all of the possible monsters in the chosen tier, even after Combat Triangle modifiers to Damage Reduction are taken into account.
