~Trapchest~
Just look in your inventory :'( my poor puzzle boss.

~Merfolk~
When you are drowning, please notice you have new drowning related skills.

~Bladewings~
This is one of the tougher boss fights, make sure you've levelled up and perhaps pick characters who do a lot of damage in the first couple of turns, like Ruby.

~Slime~
Don't forget he can 100% heal in a single move as well!

~Penultimate Boss~
You've fought these 3 before. Remember the 1st one heals and also can double your damage each turn. Then don't forget the 2nd one is also really dangerous. 3rd one only counters, so leave till last.

~Final Boss~
The actual final boss doesn't join the fight until he is injured, so take out those attendants first!
