Beyond weapons and armor, several other items are crucial for your journey. Food is essential to maintain party morale and prevent desertions. Different food types provide varying morale bonuses. Healing items (like bandages) can be used by companions with First Aid to restore health after battles.
Inventory Management is a critical skill. Your party has a weight limit, and exceeding it reduces your world map speed. Use sumpter horses to increase your carrying capacity. Prioritize carrying valuable loot for trade and essential supplies. Don't hoard too many low-value items. The Inventory Management skill (Intelligence-based) increases your party's inventory slots, allowing you to carry more without penalty.
Always carry a spare weapon or two, especially if your primary weapon is fragile. Keep a shield handy even if you primarily use two-handed weapons, as you can switch to it in emergencies. Ammunition for bows and crossbows is also vital.
