Idle Slayer is a one developer project by Pablo Leban that entered Early Access on 27 July 2020 and released on 21 December 2020, and it now carries more than 650 Steam achievements. Your slayer runs left to right on his own, jumps over gaps and kills whatever walks into him, and everything on top of that is a layer of reset. Souls buy the Skill Tree, Ascension turns progress into Slayer Points for the Ascension Tree, Ultra Ascension converts that into Ultra Slayer Points that power Stones of Time, and Astral upgrades survive the resets once you buy Astral Slayer for 500 million SP. Saves move between PC and mobile.
Picking the right build determines how your experience plays out. These builds are ranked by overall effectiveness, factoring in damage, survivability, gear requirements, and how well they scale into endgame. New to the game? Start with our beginner's guide first.

How to Play White Knight

Pros:
- Highest overall performance
- Straightforward gearing path
- Works in all content types
Cons:
- Popular pick, resources may be contested

A-Tier: Dark Wizard
Dark Wizard is a strong option in Idle Slayer.
Core Setup
| Slot | Choice | Why |
|---|---|---|
| Primary Equipment | Kishar Greatsword | A sword built around coin income rather than souls, granting coin per second scaled to Coin Potential. |
| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Souls and the Skill Tree | Every enemy drops Coins, and once you buy the Souls Flask and Soul Gatherer upgrades they drop Souls too. |
How to Play Dark Wizard
Dark Wizard focuses on a balanced approach to content.
Why this build works: Pair Kishar Greatsword with Souls and the Skill Tree and the build stops depending on a good start, so it holds up across most content. See our weapons guide for detailed equipment breakdowns.
Pros:
- Most versatile option
- Straightforward gearing path
- Works in all content types
Cons:
- Lower peak damage than S-tier
- Needs specific gear to reach full potential
A-Tier: Stone Golem

| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Ascension and Ultra Ascension | Ascension resets progress and converts it into Slayer Points spent in the Ascension Tree, which includes the Ascension CpS bonus that lifts your coin income permanently. |
How to Play Stone Golem
Stone Golem focuses on a balanced approach to content.
Why this build works: Ascension and Ultra Ascension covers the gap Boreas Longsword leaves open, so the build stays usable even when a fight goes badly. See our weapons guide for detailed equipment breakdowns.
Pros:
- Best survivability
- Straightforward gearing path
- Works in all content types
Cons:
- Slower clear speeds
- Needs specific gear to reach full potential
A-Tier: Skeleton
Skeleton is a specialized option in Idle Slayer.
Core Setup

| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | Minions and Divinities | There are seven Minions, unlocked roughly in the order White Knight, Dark Wizard, Stone Golem, Skeleton, Slime Monster, Ninja and Cyclops. |
How to Play Skeleton

Why this build works: This one leans on Minions and Divinities rather than raw numbers, and Bow is what makes that trade pay off. See our weapons guide for detailed equipment breakdowns.

- Straightforward gearing path
- Excels in its niche
Cons:
- Weaker solo performance
- Requires deep game knowledge

| Core Gear | Best available for your level | Maximizes build potential |
| Stat Priority | Balanced offensive and defensive stats | Optimal scaling |
| Key Mechanic | The Armory and Excellent gear | The Armory holds equipment across several types including Swords, Shields, Staves, Bows and Armor, and each item can roll additional bonus options on top of its base stat. |
How to Play Slime Monster
Slime Monster focuses on a balanced approach to content.

Pros:
- Unique, rewarding playstyle
- Straightforward gearing path
- Excels in its niche
Cons:
- High skill floor, punishing when misplayed
- Requires deep game knowledge
Build Progression Path
- Start with Dark Wizard: the most forgiving option for learning the game
- Transition to White Knight once you understand core mechanics and have access to Adranos Blade
- Keep a Stone Golem setup for content that keeps killing you
- Try Slime Monster for a fresh experience once you've mastered the basics
Follow our walkthrough for the optimal progression path through each area.
Gearing Tips
- Invest in your primary equipment first, since it gives the biggest power spike. See our weapons guide for rankings.
- Coins are the currency you see and Souls are the currency that matters. The Souls Flask and Soul Gatherer upgrades are what make enemies drop Souls at all, so buying them late slows the entire game down.
- Soul Reaper is the main multiplier on soul rewards, while the Ascension CpS bonus is the main multiplier on coin rewards. Knowing which one a given upgrade feeds saves a lot of wasted spending.
- Don't spread upgrade resources across multiple builds until endgame
