Lots and lots of monsters. You'll also collect treasure-reams of treasure. That's basically it. The game's accessible interface is analogous to that in Diablo. You slice, you dice, and you can choose between items on your belt with the D-pad which can then be used by the touch of a button.
Spells are available as well, and they come in the defensive and offensive varieties.
To activate a spell, a button combo must be entered. The meager spells are used by simple chains of inputs, but later they become more complicated. With a greater degree of focus on the magic of this game, this innovation would have been more important. Hacking through dungeons, you'll cut down thousands of monsters indiscriminately-sometimes thirty will fill the screen at once. The action gets quite intense at times, especially because of the great sense of control.
