also, quick question. i got like 2500 coins but still came back with "basically nothing". how much does it take to afford a doctor that can fix your organ failure?
If I remember correctly, you need certain skill level AND you need that skill to be higher than other skills to get that ending.. 50 should be enough, but you will also need it be your highest skill.
Noticeboard quests give you 2 renown each. NPC skill events give you 1 renown each. Normal quests should also give you some renown. I think there are other ways too, but renown is pretty hard to get in general.
