"You may have defeated my puppet king down on the mortal world...” “But what is a king to a god?”

This secret boss is the most difficult one, very difficult to slay. In order to activate him you have to:

1. Spare all the tuba bosses

2. Have all the tuba bosses in your party

3. Attack the tuba king with all your mana (Using the ultimate spell from tuba wizard)

he is very strong and he will one-shot you with any of his spells. To defeat him i recommend you to max the tuba heavy machine gunner and tuba artillery, because of their large range you can dodge his attacks and attack him withouth getting closer.
