King Arthur Cheats

Equip Gwen with one healing item (such as Bloodring). Have Arthur kill any weak enemies. Then, have him go around the corner where he is safe and let The Shaman shoot a meteor. Remember to dodge. Finally, get behind the black circle and shoot. Because you are beyond his range, he cannot hit you. If he teleports, just let him shoot a meteor and continue from there.
