Absolutely pathetic game. Been playing for nearly two months now. Spiders Den is a complete waste of time as I have never obtained anything useful, all you get is common and uncommon rings and no amulets on stage 5 which I find hard to believe. Also, the shards are absolute rubbish. Don't get your hopes up. You hardly ever get an epic champion from any shard and rare champions are hard to come by. I've experienced major issues with the game. Artifacts are nearly impossible to upgrade.
