Tips for Clearing Challenge Difficulty Zones

• Chocolate Volcano: Focus on traversal and puzzle-solving; enemies are manageable even at lower levels.
• Milk Ice Mountain (Lv 60): Bring a balanced team with healing and crowd control. Watch for ice-element enemies that can freeze.
• Amber Sugar Lake (Lv 75): Poison and fire traps are common. Use characters with cleanse abilities.
• Crimson Castle (Lv 90): The hardest area. Prioritize single-target damage for elite mobs and the final boss. Shinku’s Ultimate is especially effective here.

Once you complete Challenge difficulty in all zones, the sealed crystals are removed, opening full exploration and rewards.
