Level 3 Normal
Easy Monster: 28,988,333 power
Hard Monster: 79,408,248 power
End of labyrinth: 142,660,325 power
1st bonus boss 1,389,590,030 power
2nd bonus boss 362,763,972 power
3rd bonus boss 365,129,039 power
4th bonus boss: 605,131,837 power (uses a substitute)

The 10pt monster, and all bosses start the match with full morale bars.

There is a very significant leap in difficulty from Act 3 Easy to Normal.
You'd need lots of imagination to kill the bonus bosses.
