As you all know in the Middle Ages swords (and even more so armour) were rare and very expensive, and what happens when we bring the spoils of battle to the city? If you sell your sword, you can't even buy bread. It's not normal. I've increased the selling price, and now if you take out a good armour from the battle - you can repair it at the blacksmith, sell it and stay in the profit. The key word "good", armour strength below 90, in the scheme of repair-sale, will bring only losses. 
In order to balance the mod I also increased the purchase price.
Beast slayers have an interesting debuff, for them prices are 10% higher, so in this mod prices are 110% higher. You will earn more, but also purchases on the market will be more expensive, but you will more often collect armour from enemies, and sell for good money, now selling armour has become profitable.

And to collect all the loot, even broken to 0% - there is a mod "Battle Cleanup", as well as I recommend mod "Get Loot Without Last Hit" with it you will have access to the loot, even if the enemy finished not you, but an ally.

Here is the full code of the mod:
this.World.Assets.m.BuyPriceMult = 2.1;
this.World.Assets.m.SellPriceMult = 4.0;
this.World.Assets.m.ExtraLootChance = 0;
this.World.Assets.m.FootprintVision = 1.5;

Don't be alarmed by a sell multiplier value of 4, it's not a problem, it's still 20% below the standard price, if something costs 1000, you'll sell it for 675 and traders will sell it to you for 2200. this will allow Beast Slayers to sell monster parts for a good price.
