the best combination i have found after playing this for 2 days, is to equip all your champions with melee lifestealing weapons, with high crit and high hp.
Angel's alliance is definitely bugged, the 25% mana upgrades looses effect once you upgrade Mana Shower. which is dissapointing considering you made it pretty far before being able to get that upgrade...
Thank you for this game, i always wanted too but struggled learning some basic philosophy without reading long lines of text that seem to head nowhere.
