First map of Riddle of Gnome Lords, the player wins when one enemy is still alive. Also, Unholy Wellspring + Raging Strike is hilarious, especially when he does it twice in the first round.
The first battle on Into the Black Forest has me needing six stars, but only has as enemies 2x Tall Beech Trees @ two stars each.
The first fight in the Viscous Tombs wants 6 stars, but the opponents are only 3 oozes @ 1 star each.
