This should be a 5-star game. This game is by far one of the best, most engaging, and fun mobile games I have ever played. Like Path of Exile on my phone. Except PoE was not pay2win. This is w/o a doubt a micro transaction pit. The game is great. Want to buy an extra storage slot? That'll cost you about 700 gems, which there is nearly no way to make w/o buying them. So you have to buy them. Oh and it's like $20 for 500 gems. So that's a big ripoff. This will eventually kill the game. Too bad....

I really like the game it's pretty smooth as far as graphics go, and I have not encountered any bugs so far. Story is actually interesting, and I usually skip story lines. At first it was a bit difficult to navigate but I got a hang of the rune system and how they work, which is easy as you get the hang of things. Potions are keeping me alive, rarely have any deaths. Only thing I would like to see, is a way to earn diamonds without spending a whole lot. Other than that, pretty solid game so far!

The game is beautiful and the voice overs are pretty good. The combat leaves something to be desired. I made 2 characters and both of them ended up feeling clunky. It felt like I couldn't aim easily on my archer character and my summoner felt like she had to stop and go every few seconds just to set up her minions. It's early game so I'm sure the summoners skills will iron out but it left me feeling frustrated early on. I ended up turning on the auto combat function on just to play.
