SurvivalXtreme again

A while ago, I made a post about SurvivalXtreme. I deleted it. Now, I am making another one on how to beat it with one player only.

You should try to get as much resistances as possible. Start with a peasant, and get curse and holy rage. Increase resistances and the power of those attacks, and level to a royal guard. Once you have 100% resistance to all of the bosses' attacks, attack them with holy rage. You will easily win.

I tried it once and won by turn 42. I stayed near the shop area until after turn 20. I was a peasant with 800 gold.
