Oathkeeper

Oathkeeper: A Guild Master's Call

The realm is fractured. The desperate cry out for leadership. Will you answer the call?

Welcome to Oathkeeper, a deep, systems-heavy idle ARPG simulation where you don't play the hero—you manage the entire guild. Built for min-maxers, loot enthusiasts, and theory-crafters, Oathkeeper strips away the grind of traditional action RPGs and distills the experience into pure roster management, deep itemization, and rewarding progression loops.

Recruit wandering adventurers, outfit them with powerful, procedurally generated artifacts, and deploy them on perilous expeditions to bring gold and glory to your halls. But beware: as your reputation grows, the requests that reach your desk will demand flawlessly synchronized raid groups and flawless tactical execution.

✨ Core Features

• Dynamic Hero Roles: Heroes aren't locked into rigid boxes. A fragile spellcaster can transform into a sturdy frontline defender with the right plate armor. A hero's Active Role (Tank 🛡️, Healer ✨, or DPS ⚔️) dynamically shifts based on their dominant stats, turning your inventory into an ever-evolving puzzle.
• Deep ARPG Itemization: Chase the perfect drop. Loot ranges from Common rusted blades to glowing Mythic artifacts. Discover gear with randomized stats, distinct Suffixes/Prefixes, and rare innate traits like Dragonslayer, Multitasker, or Vanguard that can completely change a hero's utility.
• Perilous Expeditions: Match your idle heroes to the required roles on the Expeditions Board. Calculate your party's total power, weigh the risks, and roll the dice. Success yields riches and progression; failure sends your heroes back empty-handed.
• The Arcane Reforger: Don't throw away that near-perfect sword! Break down unwanted Epic, Legendary, and Mythic gear into Arcane Dust. Spend it to reroll a weapon's stat distribution or transmute entirely new traits onto your favorite cloaks.
• Guild Expansion: A thriving guild is an expensive one. Invest your hard-earned gold to expand your Roster capacity, upgrade your Vault, entice elite patrons to the Wandering Tavern, and level up the Legendary Merchant’s shop to gain access to devastatingly powerful wares.
• Active Crafting Workshops: Put idle heroes to work. Assign your Blacksmiths, Tailors, and Enchanters to the workshops to forge gear over time. Upgrade your stations to increase capacity and guarantee higher-quality yields, including the chance for incredibly rare Masterwork items.

A Note from the Developer (Nerdzilla): Oathkeeper is a passion project built by a lifelong gamer (and father of two). It is the exact game I've wanted to play for years—a love letter to the classic days of min-maxing raid groups and chasing legendary loot.

I also want to be completely forthright: this game was built with the help of generative AI. I know that can be a controversial topic, but AI didn't give me the idea for this game; it gave me the opportunity to finally build it. I approached it like a tutor, letting it teach me the code so I could bring this vision to life. If you have even a fraction of the fun playing it as I had building it, the adventure was a success.
