Every new gamer of this game read me.
I’ve seen several people complaining about durability.
There are several ways to win money: Fighting of course, selling and doing jobs.
Each time you win 5 times in a row you can claim a victory prize that consists of around 250 silver and a small potion.
Skirmish doesen’t earn much money.
ALWAYS do something in Trade, either it’s gathering or a job.
Meanwhile your gathering or doing a job, fight in arena and claim lot’s of victory prizes.
Once you start repeatedly doing this don’t forget to repair your stuff every now and then because it degrades every time you lose, and your sword degrades every time you win.
Your “green” items can be upgraded to do more damage, so spend some silver in that.
