Both your rune knights and monsters can level up, and in doing so, gain new abilities and have a boost in stats. Yes it is possible for your rune knight to vanquish a dragon. But there's one con to the gameplay. I'm surprised the other reveiweres didn't mention this. I'm playing the english version.
Graphics are ok.
The 3D scene appears when a unit takes on another unit. I thought it was nice. But of course, the 2D units needs to be improved, but they're ok too. The sound was ok, especially when you are checking your castles and army. The gameplay is brillant with the quest and attacking and defending your castles,especially the class change setup.
