Game Overview

Slay All Bosses: Idle is an incremental RPG that transforms a humble level 1 hero, initially struggling against mere goblins, into a legendary slayer capable of conquering the deadliest adversaries. The game features satisfying auto-battles where your hero fights independently, attacking foes and unleashing powerful Weapon Skills tied to the equipped weapon. Once these skills are used enough, they become permanently learned, allowing you to freely swap weapons without losing progress. After each battle, you earn currency to advance through a detailed skill tree filled with nodes that boost stats or grant passive abilities, reshaping your hero’s playstyle and strategy. As your hero levels up, Skill Points become available to unlock Weapon and Skill Upgrades, enhancing stats and improving abilities with effects like status infliction, area attacks, or cooldown reduction. These upgrades turn your skills into devastating tools of destruction. To survive against enemies wielding lethal skills and dangerous status effects, you can equip accessories that grant passive bonuses and resistances. Over time, these passives become permanently learned and can be mixed and matched, limited only by your hero’s Ability Points, enabling you to adapt your build for any challenge. With 15 challenging boss battles and a smooth progression system blending character growth, weapon mastery, and skill enhancement, Slay All Bosses: Idle offers a strategic and rewarding gameplay experience.

  • Strategic auto-battles with permanent Weapon Skills
  • Deep skill trees for character and gameplay customization
  • Weapon and Skill Upgrades to enhance combat effectiveness
  • Accessories providing passive bonuses and resistances
  • 15 challenging boss battles to test your hero’s strength
