From Melvor Idle

Alpha v0.18 - (14th December 2020)

Slayer 2.0

Slayer has been reworked with a new progression route, and an increased variety of content and gear.


Slayer is a skill that has the ability to introduced players into new mechanics and challenges that other skills cannot do. The current system of Slayer did not really provide the variety we were after, and we knew we had to change it.

The new Slayer takes the existing fundamental mechanics and turns them into something that we feel is more enjoyable and more rewarding.

Players will see a tonne of new content including brand new high level monsters and very powerful items. The progression from early levels will feel much better, and Players are given more control to train this Skill.

Slayer Tasks

These are now broken down into 5 "Levels" that can be chosen when selecting a new task. These are categorised based on Enemy Combat Level.

They also cost Slayer Coins to select a new Task or when skipping your current task (but are free when completing a task and being assigned a new Task from the same Level automatically).

  • Easy - Combat Level 1-49 - Free (Unlocked at Slayer Level 1)
  • Normal - Combat Level 50-99 - 2,000 Slayer Coins (Unlocked at Slayer Level 25)
  • Hard - Combat Level 100-199 - Costs 5,000 Slayer Coins (Unlocked at Slayer Level 50)
  • Elite - Combat Level 200-374 - Costs 15,000 Slayer Coins (Unlocked at Slayer Level 75)
  • Master - Combat Level 375+ - Costs 25,000 Slayer Coins (Unlocked at Slayer Level 85)

Slayer Task Extensions

Slayer Tasks can be extended once at a cost of Slayer Coins by clicking the Extend Slayer Task option in the Slayer Task Panel.

New Slayer Areas

There are 5 new Slayer Areas to tackle, all with brand new monsters and challenges. These Slayer Areas also have Area Effects that apply a debuff to you when fighting Enemies in it. These are the Runic Ruins, Arid Plains, Shrouded Badlands, Perilous Peaks, and Dark Waters.

New Slayer Dungeon - Miolite Caves

Miolite Caves is a new mid-game dungeon with 7 Monsters. Rewards the new Miolite Armour and Miolite Sceptre.

Miolite Armour is a Hybrid Melee / Magic Armour set. Very similar to Ice Armour which is a Hybrid Melee / Ranged Armour set.

New & Updated Slayer Gear, Progression & Requirements

The Slayer Gear in the shop that you can purchase has changed in many ways, which includes the brand new Master Tier of Slayer Gear.

Master Slayer Gear

You now able to acquire Master Tier Slayer Gear, which is much better than the Elite Tier.

This Tier of Slayer Gear provides Area Effect Negation, Damage Reduction, as well as increased chance to double dropped Loot.

New Gear Progression

It felt wrong allowing players to ignore complete tiers of items, and this didn't feel right in terms of progression. This has now changed to address this issue.

Players are now required to upgrade the Slayer Gear pieces, starting at Basic, to reach the highest tier of Armour available.

This is done by purchasing the new Slayer Upgrade Kit within the Slayer Shop for the respective tier, and combining it with the desired Slayer item to upgrade it.

Updated Slayer Gear & Benefits

With the inclusion of Slayer Task tiers, Players are now required to complete a set amount of Slayer Tasks before they are able to purchase the Slayer Upgrade Kits.

This also means we have made Slayer Gear just a little bit better in general.

These new benefits & requirements are:

  • Basic Slayer Gear - Still 10,000 Slayer Coins - Each piece has 10% Area Effect Negation - Completion of 20 Normal Slayer Tasks required to purchase.
  • Strong Slayer Gear - Requires Slayer Gear Upgrade Kit (Strong) (50,000 Slayer Coins) - Each piece has 20% Area Effect Negation - Completion of 30 Hard Slayer Tasks required to purchase Kit.
  • Elite Slayer Gear - Requires Slayer Gear Upgrade Kit (Elite) (200,000 Slayer Coins) - Same Price - Each piece has 30% Area Effect Negation & 4% Damage Reduction - Completion of 40 Elite Slayer Tasks required to purchase Kit.
  • Master Slayer Gear - Requires Slayer Gear Upgrade Kit (Master) (1,000,000 Slayer Coins) - Each piece has +3% chance to receive double loot from slain monsters or Thieving & 40% Area Effect Negation, 40% Area Effect Negation & 6% Damage Reduction - Completion of 50 Master Slayer Tasks required to purchase Kit.

New Slayer Shop Items

There's a bunch of new stuff for you to purchase in the Slayer Shop, such as Basic Resupply, Auto Slayer, and more.

Updated Slayer Cape

The Slayer Skillcape has been updated to fit in nicely with all the above changes!

NEW: Bypasses Slayer Item Requirements from Slayer Areas. 60% Area Effect Negation. +5% Damage Dealt to Enemies on Slayer Task.

Endgame Content Pt.2

This update includes Part 2 of the storyline revolving around the Gods, as well as a brand new dungeon for Players to face.

The story so far

For those of you who don't know - there is a storyline in Melvor Idle. The first of this was introduced in Alpha v0.15 with the God Dungeons.

When you load into the game, you may be provided with one or two books to read, depending on your current progress.

I urge you to have a read of these books as they can provide an insight into why you're fighting the Gods, and what it is all leading up to within this update.

Into the Mist

Into the Mist is the brand new Dungeon, and the first to be classed as Insane difficulty. Upon defeating the Fire God Dungeon, you will be provided with Part 2 of the storyline and will also unlock access to this Dungeon.

You are required to fight through various random enemies from the game until you reach the final Boss.

The Final Boss is a 3 Phase battle which will test your preparation and skills in each Combat Style ( Melee, Ranged, and Magic). Be sure to pay attention to the Enemy Passives, as it will tell you which Combat Style you must use.

This Dungeon is extremely difficult, and there is a very strong chance you will NOT be able to idle it. Luckily, you only need to beat the Dungeon once to claim all rewards.

Dungeon Mechanics
  • Most Enemies in this dungeon are Afflicted. Afflicted Enemies gain +20% Flat Damage Reduction.
  • Upon being successfully hit by an Enemy, you gain a stack of Affliction. Each stack reduces your Maximuim Hitpoints by 1% of your original Max HP. This resets after defeating the Enemy (Multi-hit Special Attacks are classed as ONE attack). Affliction is capped at 50 stacks.
  • The first 20 Monsters in this dungeon are randomised. Any Monster in the game, including those in Dungeons, can be selected if their Combat Level is between 165 & 677 inclusive. Monsters found in Dark Waters Slayer Area cannot be selected.
  • The final Boss is a 3 stage fight, so be prepared.
  • You are required to use a specific Attack Style ( Melee, Ranged, and Magic) for each Phase of the final boss. Pay attention the the Passives to know which style to use.
  • Upon reaching Phase 1, 2 or 3; The fight will pause and allow you to read all the information. You can then press the button to continue the fight.
Dungeon Rewards
  • Item - New Dawn (it's a book, have a read)
  • Grant Access to the Dark Waters Slayer Area.
  • Unlocks the new Combat Passive Slot, one for each equipment set. This is a new slot where you can equip most Combat Items with passives and gain their benefit during the fight.
  • You cannot equip Weapons, Skillcapes (Including Max & Completion), Skilling Items or items that are already equipped in the same set to this slot. Some other items cannot be equipped as well.
  • Hovering or clicking an item in the bank will mention if it can be equipped to the Passive Slot.
  • You only gain the item's Passive, not the item's Standard stats (this includes flat Damage Reduction the item contains).

Infernal Stronghold

The 3rd new Dungeon added to the game is the heavily requested Infernal Stronghold. This is an upgraded, more deadly version of the Volcanic Cave.

Completing this Dungeon will reward you with the Infernal Cape as well as an Infernal Core. This Core can be used alongside your Dragon & Ancient Claws to upgrade them into the Infernal Claw.

This Dungeon requires 100 Completions of the Volcanic Cave to enter.

Mastery Pool Quality of Life

The Mastery Pool buttons are now colour coded when spending Mastery Pool XP!

  • Green means you can safely spend without losing benefits.
  • Yellow means you can afford it, but you will lose a Mastery Checkpoint bonus in the process.
