A Moment of Serenity

A Moment of Serenity is the fourth stage of The Legend Ends.

Battleground

 * Mr. Angels are the peons for this stage, and spawn at a mild rate (1 every 10 seconds).
 * When the enemy base's HP reaches 99%, a trio of Mr. Angels will spawn with Boraphim and Sunfish Jones.
 * During the boss fight, Winged Pigge and Cala Maria will spawn as soon as there's room for them (in other words, when some of the Mr. Angels are killed).
