Your party is the one of the most important aspects of the game; within it you can hire troops (from villages) and secondary heroes who will help you in battle. NPCs are important because they cannot die in battle (they just get wounded). There are sixteen heroes in the game you can hire from taverns. It is important to level up your Persuasion so you can handle inner party disputes, as not all heroes will like each other.
Morale influences your moving speed and when it becomes low your troops will start deserting. You can increase your morale by winning battles, tournaments, having a variety of food, completing quests, razing villages and raising your leadership skill. You can lose morale from starvation, losing battles, and failing quests (the last one is actually true for many NPC heroes). Morale of nation-based troops is also greatly negatively affected if you are waging a war against their home nation. Also, fighting more than 1 or 2 times a day will lower morale.
- Base morale: your base morale will always be 50.
- Party size: the more troops you have in your party, the higher the morale penalty will be. Note that when removing party members, this penalty will decrease by 1 each, but a temporary 1 point penalty will be incurred to Recent Events. This means you are left with no immediate net change.
- Leadership: morale bonus provided by your Leadership skill.
- Food variety: quite self-explanatory, every type of food has a morale bonus in its description.
- Recent events: any events like winning tournaments, battles, or completing quests will give you a large morale bonus.
- Base size: the base size of your party is 10. (Base size of 30 in Warband 1.160)
- Leadership bonus: every level in the Leadership skill will increase your party size by 5.
- Charisma bonus: every level in the Charisma attribute will increase your party size by 1.
- Renown bonus: your renown heavily effects your party size. For every 25 renown, party size is increased by 1.
- Lord: being a lord (having at least one fief) adds 10.
- Marshall: being the marshall of the troops of a sovereignty adds 20.
- King: being the king of a sovereignty automatically adds +100 party capacity.
Note that the last three modifiers only affect NPC parties.
Wages will be paid to your troops every 168 hours, which is seven days. If you don't have enough money to pay your troops' wages, your party will lose morale and you will incur a debt. Wages are primarily based upon your troops' level, but then several other calculations are performed before reaching the final amount.
