Here’s the break down: There are (48)6* characters If you need a copy of each that’s (96) 5* heroes Then you need (4) 5* character sacrifices for each evolution That’s (192) other 5* heroes That makes (288) 5* heroes needed total. To get (288) 5* heroes you need a copy of each 4* character. That’s (576) 4* heroes Then you need [on average] (3) 4* sacrifices for each evolution That’s (1728) other 4* heroes That makes (2304) 4* heroes needed total. It takes (3) 3* sacrifices and no copies for each 4* evolution for a total of (6912) needed 3* plus the (2304) heroes you are trying to evolve. Thankfully it is easy to get the 3* sacrifices from using loot tickets in the dungeons. This means; If you “happen” to summon/receive in a drop all 80 starting forms of each character (not including what you actually need for the altar Gods you can summon), you will have to perform 2640 evolutions to get every characters final form. If you did 1/day... roughly 7 and a half years of playing this iPhone game... Not really worth it which is unfortunate cause it is a fun game. Hope this is enlightening. Cheers Also to be fair, I’m cheap and am never going to spend money on a free game. So I do think they/you are trying to push gamers to spend more real money. That is fair it’s just unfortunate. So therefore those like me will have a potentially tough time getting through most of the game without spending any real money.
