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.
