Cave of trials number 6 easy win =
2 golems and 1 wolf in front hitting the goblin bros. keep using regeneration on them and they will never die. have the others in the back firing on them. Try to get your mana to 100 before sending them off so you can build healing towers next to the golems and the wolf.
The trials aren't too hard. All you have to do is build a castle or 2 at the start and the rest healing. And then put the melee in front of the castle and the ranged behind. Then draw the boss there.
Fix the combo system. That is the only way to win money, and it goes away because you have to wait for the enemies to show up. This is a little redundant, hmm? So do something about it. I am giving it a 3 for this reason.
