- Slavery: Use the buyed slaves to make hard work, and be able to capture your own slaves.
- Conquest: Be able to conquist any city and camp in the game, by defeating the guards or/and a "city leader" (example: conquest Rebirth by defeating a leader and the guards, the leader could be a new NPC or a inquisitor, whatever you want)
- Surrend: Be able to surrend yourself or any npc's without fighting.
- Mercenary: Be able to accept works from other npc's as mercenary (example: defeat a dust bandit camp)
- Markers: Be able to put marks in the map, and the missions too.
And i think that's all, the essentials in my opinion are Slavery and Conquist.
