So I decided to play the game and got to around lvl 175-200, then started looking up tips/tricks etc. By the time I found out about upgrading rarity the right way I had beat about 4-5 daily bosses so the next one I had to beat was too strong for me to ONLY have 3 heros hired and upgrade rarity. Now I'm kind of lost as to how I should go about my situation? Should I keep the grind on souls and keep restarting until I'm able to beat the daily boss with 3 heros? Or is there a different way? Ant info helps, thanks!
