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.
Your choice of equipment defines your damage output and playstyle. This guide ranks every major option, explains what makes each one strong, and tells you which builds they pair best with.
Equipment Rankings
| Equipment | Tier | Best For | Notes |
|---|---|---|---|
| Adranos Blade | S | Slayer Point farming, long offline sessions, and dimensions that actually contain Electric type enemies. | A sword whose base stat is Souls Bonus, giving a flat percentage improvement to soul gain. |
| Kishar Greatsword | A | Coin focused runs, Chest Hunt heavy play, and anyone chasing Emerald spawns. | A sword built around coin income rather than souls, granting coin per second scaled to Coin Potential. |
| Boreas Longsword | A | Dimensions with Fire type enemies, elemental focused farming, and as a swap in item rather than a permanent equip. | A sword whose base stat is a Fire type Souls bonus, with additional options for coin per second, general Souls bonus and more Fire type Souls. |
| Bow | B | Raising kills per second once collision damage alone stops keeping up, and any dimension where enemies are spread out. | An Armory weapon type that changes the loop rather than the numbers. |
| Staff | B | Mid and late game power, players sitting on crafting materials, and anyone told to level Shields and Staves before touching swords. | One of the higher value Armory types, generally levelled before swords. |

Equipment Progression Path
The order you should acquire equipment as you progress:
- Starting gear → Enough to clear Mystic Valley
- Kishar Greatsword → Your first real upgrade, available early
- Boreas Longsword → Mid-game upgrade with good scaling
- Adranos Blade → Best-in-slot, aim for this by late game
- Upgrade to max → The power spike from max upgrades is enormous
Equipment Tips
- Always upgrade your primary equipment before diversifying. One strong option beats three mediocre ones.
- Match your equipment to your build's stat priorities for maximum scaling.
- 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.
