Shadows of Corruption is the fourth section of the battle mode. It is unlocked after the player completes Chapter 2 of Story Mode.
Currently, there are 23 bosses in this section.
Elemental Bosses[]
Tower Bosses[]
Shadow Bosses[]
Shadow Event[]
Strategy[]
The easier bosses are Ohige Alien, Clover, Luni, and Meguna because most of their attacks are lower AOE (Area of Effect) damage. Make sure to bring a healer, 2 MP Boosters, 3 Ultimate Debuffs, and 1 Ultimate Buff. Also, make sure all your pet buffs are only HP and Defense.
It is best to find units with high HP and Defense; however, teams can be adjusted to finish quicker based on their levels and skills.
If you are challenging any of the element bosses, take into account their strengths and weaknesses; should you have an important unit of an element the boss is strong against, you're not going to have a good time. Try adding units of an element the boss is weak against, e.g. using wind units against Cykopath, who is a water element boss.
Recommended level: At least 50 or more
