This game is very similar to diablo and other hack and slash games. But its skill system is innovative...
The item enchancement is probably the top of this game. Equipement can be enchanced with material and runes. The runes give bonuses and if you arrange them in proper manner you get rune word which grants even a bigger bonus.
It has one of the best alchemy sistem i have yet to see. you can transmute anyting, items, potions, scrolls. The camera can be akward at first and i recommend you to have a mouse with a weel. with it you can easily rotate the view which will make the game much more enjoyable.
The difficulty of combat depends on your skills set. but it is not easy. Also if you manage to kill many monster at the same time you get an bar (similar to adrenaline bar) which enables you to get more and more xp from killing monsters.
