Relic Dungeon is a 2D pixel-art auto-battle RPG about building a party of three, exploring ancient ruins, and finding equipment to make your team stronger. BUILD YOUR PARTY Choose from seven basic classes: Warrior, Mage, Guardian, Martial Artist, Rogue, Cleric, and Strategist. Combine damage, defense, healing, speed, ailments, and support to overcome each dungeon. UNLOCK ADVANCED CLASSES Train both required basic classes to JOB Lv.100 to unlock Tactical Knight, Spellblade, Paladin, Ninja, Sage, or Arcane Strategist. Advanced classes can equip two weapons and bring new skills to your party. EXPLORE 40 STAGES Fight through multiple floors and waves, then face bosses with unique mechanics. Check the Codex for enemy traits and equipment drops, and adapt your build to each challenge. FIND YOUR NEXT UPGRADE Collect weapons, armor, accessories, and boss relics. Random rarity and affixes offer new ways to strengthen your team. Enhance your best items, sort by newest first, and save different formation presets. AUTO-BATTLE WITH TACTICAL CHOICES Characters act according to SPD. Normal attacks charge skills, while you choose attack targets and switch between each character's two skills. KEEP FARMING WHILE AWAY When you leave the app during AUTO farming, background progress is calculated when you return. Review your run count, gold, JOB EXP, and acquired equipment.
