Stronghold – “The Barbarian Seven” [Campaign 6, Mission 3]

A solid strategy game. But I decided to take a more challenging approach. I almost always play with a single hero. This time, I wandered around the map, fending off attacks from all sides. I'll spend a week clearing the map, then a week fighting – and I'll keep doing that until I've mastered the entire map.
As a result, I've gained almost two dynasty ranks and upgraded two weapons from level 4 to level 5. Honestly, it almost feels unbalanced. I haven't even finished the first campaign, and I've already almost reached platinum dynasty level. The only problem is that I won't have enough money to buy supplies >_<

For me, the number of heroes depends on the size of the map, but so far, I haven't had more than three. Yes, about "supplies" (I assume you mean the Shrine of Wishes), the developers are probably drawing on their experience from online hypermarkets – a wide selection, accessibility, you buy all sorts of junk, and then you regret it... I'm just holding back on this Shrine for now; what should I buy? Maybe I won't have enough coins later for something really useful? A specific example: I reached the silver rank, and the Urgash's Will weapon became available. Do I need it? No? Maybe it will appear in a campaign later?
