once you get a 2%-mana-sucking item. you can learn Healing(lvl1) and Lightning(as high as possible), start putting 5/5 in intelligence at each lvl up...
...and shorlty all you would need to do is run around casting lightning: killing everything in short with infinite mana, while moving so to be unattackable.
2/5, needs better balancing.
ps. i've encountered the 2x2map bug, please fix it! after these two modifications the game would be great!
