About Slay All Bosses: Idle
Slay All Bosses: Idle is an incremental RPG where you take a lowly level 1 hero, barely capable of handling a pack of lesser goblins, and forge them into a legendary slayer able to defeat the deadliest of foes.
Satisfying Auto-Battles
Your selected hero fights automatically, attacking enemies and unleashing powerful Weapon Skills. Weapon Skills are tied to the weapon you have equipped, but after enough uses they are permanently learned, allowing you to freely swap weapons and experiment without losing progress.
Player Driven Character Progression
After every battle, you earn currency used to advance your hero’s skill tree. Skill trees feature a variety of nodes, from raw stat boosts to gameplay-altering passive abilities that redefine how your hero plays.
Weapon & Skill Upgrades

Each time your hero levels up, they gain Skill Points used to unlock Weapon and Skill Upgrades.
Weapon Upgrades provide additional stat bonuses when equipped.
Skill Upgrades allow you to enhance your learned skills even further. You can add status effects, strike all enemies, and/or reduce cooldown times. Spend Skill Points to transform skills into devastating tools of destruction.
Additional Passive Abilities & Accessories
Your hero will face enemies armed with lethal skills and dangerous status effects. Equip accessories to gain passive bonuses and resistances. After enough battles, you’ll permanently learn these passives and can equip them freely, limited only by your hero’s Ability Points (AP). Mix and match learned abilities to adapt to any challenge.
