Man! indeed the 1st epic is hard! I've tried the mana pool thingy but i dont get enough gems to defeat last waves, so when bloody boss arrives to the end my mana is 2k or below... guess i'll need to iprove that strategy
The first epic isn't hard, just be sure to get a good purple and only use level 4+ gems because any weaker will no matter what do no damage to the some of the last waves or the epic boss
