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.
Choosing the right build shapes your entire experience. This guide breaks down every option: what they're good at, what they struggle with, and which one matches your playstyle. For optimized builds with full gear sets, see our builds guide.
