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.
Resource management and crafting determine how quickly your power scales. This guide covers what to prioritize, where to farm, and how to avoid wasting resources on the wrong upgrades.
Crafting Priority List
The order you should invest resources:
| Priority | Target | Why |
|---|---|---|
| 1 | Primary equipment | Biggest damage increase per resource spent |
| 2 | Core build gear | Enables your build's key combinations |
| 3 | Defensive upgrades | Survivability for boss fights |
| 4 | Secondary equipment | Situational options for specific content |
| 5 | Consumables | Temporary boosts for hard content |

Upgrade Path
Early Game (Mystic Valley to Hot Desert)
- Upgrade your starting equipment to functional level
- Craft basic defensive gear
- Save specialty materials, since you'll need them later
- Focus on Kishar Greatsword once accessible
Mid Game (Factory)
- Push Kishar Greatsword to mid-level upgrades
- Start collecting materials for Adranos Blade
- Craft situational consumables for boss fights
- Upgrade build-specific gear pieces
Late Game (Frozen Fields to Funky Space)
- Max out Adranos Blade. This is your top priority
- Complete your build's core gear set
- Craft endgame consumables
- Optional: upgrade secondary equipment for variety
Crafting Mistakes to Avoid
- Spreading upgrades across multiple equipment: Focus one weapon to max before diversifying.
- Hoarding materials: Use them. The game provides enough if you farm efficiently.
- Upgrading the wrong gear: Check our builds guide before investing.
- Ignoring Factory farming: This area has the best resource-to-time ratio in mid-game.
- Crafting consumables too early: Save specialty materials for late-game recipes.
Resource Efficiency Tips
- 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.
- Farm Factory during mid-game for the best return on time
- Check the walkthrough to know when each resource becomes available
- Match your farming route to your build. Some classes farm faster in certain areas
