well, i've searched for walkthroughs on this game, but nothing big ever came up, i did however find a link the the maps in the game they are in this website www.ageofgames.net
I forget. I'm not on the computere where I beat that game, so I can't say for sure. He's either weak against light or darkness (maybe neither), so either wear that amulet or not wear the amulet that gives light attribute to your attacks.
Well, if you've got the maps, there isn't much else help to give. It's simply just spamming the the attack to beat the enemy.
Keep all weapons/items that drop from the bosses because they have an additional attribute (earth, heavy, light, etc.) which is useful against later bosses.
Put all the points to improve attack strength since the other stats are rather useless.
The flag and the King's Tower are on the same map.
