Stuck in Episode 4? Tips & Fixes
Level Up and Push for Breakthroughs

Level up and push for Breakthroughs according to the boss's recommended level. By leveling up, you can increase your overall stats.
Craft Arm and Leg Equipment

The Arm equipment's Main Stat increases attack power, directly boosting your damage output. Leg equipment can also increase damage when equipped on a character of the matching Role, so prioritize getting arm equipment first, followed by leg equipment.
Enhance Artifacts

Enhancing your equipped Artifacts also raises your stats. Prioritize enhancing the equipment of your main damage dealers and Assassin Role characters.
Enhance Character Skills

Once you've finished enhancing stats, work on enhancing skills as well. It's especially recommended to prioritize enhancing the Special Skill and Switch Skill as they are used frequently.
Change the Difficulty to "Path of Dawn"

If you want to enjoy the story without getting stuck on boss fights, lowering the difficulty is also a recommended solution. By selecting "Path of Dawn" in the difficulty settings under "Controls", enemy damage and health will be reduced.
