Blood And Iron covers a huge amount of change. The mod significantly complicates the combat system (enemies are more aggressive, the window for blocking is reduced, and stamina is restored longer and more is spent), the system of random encounters (there are many more encounters, and they take place much more often). In addition, 38 new perks have been added and the exclusivity of perks has been canceled - you can combine any perks, creating new and unpredictable ones. Inventory and equipment have also been changed - the repair kit is heavier and more expensive, but will last longer, new horse armor items have been added, and merchants have more gold, but a higher price. Resellers will buy stolen items at discounted prices.
