2 star is to kill everyone but not lose any unit to death?

Kinda forgot how the system works LOL

attempted Depth of the Maze and Unexplored Territority

did 1 star Depth of the Maze after everyone died :V - thought for sure I can kill the red dragons

the green dragons dies easily to a CC50 Calliope

no way to kill the mummies and they are ranged (which adds more trouble

can probably figure out how to kill a Lich if I have survivors in place b/c a lone CC66 Cornelia w/o healer can't kill the Lich fast enough on her own

We got two Lichs - shit

couldn't 1 star Unexplored Territority b/c of Black Goblin archers - almost had it
