Needs help – Bladelords - fighting revolution Review

I enjoyed this game it’s simple and fun.The problems are that it takes up to 24 hours for one upgrade that doesn’t make any difference.A big one is I’m literally stuck.I don’t have enough money for an upgrade and the bosses are ridiculous.I have to try to get a three star character out of the crystals to advance.May I add that it is either rigged or a one percent chance.It is also easy for this to happen to any player.Thanks.
