race track is the easiest map in the game. and it gicves like 950 gold everytime you beat it.
just start from the back. upgrade everybody to lvl 2 only. and when everything is full star upgrading them higher.
final boss is a bit too easy
right now i have 3 forest guardians and 2 red dragons attacking him, his damage is worthless, sucks that he absorbs ranged tho coz my rangers are outside of his range and he isn't moving because of my guardians
