This is supposed to be complete quest-orientated walkthrough for the game Inquisitor.

Since my English is not good, I will try to be brief and make it easy to understand.

If anyone find anything I failed to find or mistakes I made in the article, please tell me and I will correct them.

There are still several questions which still need answers:
1. As I myself only finished the game as Paladin, I don't know who gives the promotion for the other classes. I'm eager to fill these gaps with the knowledge of players with other classes.



A mark of asterisk after the name of the quest means this quest is related to main plot.

ACT II Walkthorugh Problems:

Your walkthrough says "The Robbed Ring" but that quest is NOT listed.

Also says "after Yulliette is executed" but how, or what quest, does Yulliette get executed?

And says "go to the "Devil's Cavern" but it is NOT on the World Map.

Also says "during the quest Missing Girls" but quest is NOT listed.

You can find these quests listed in the second part of zeranix's walkthrough:
http://www.gog.com/forum/inquisitor/complete_quest_walkthrough_part_2 It's the classic - once you have enough evidence to arrest her, put her in jail, interrogate her and when she confesses and the story moves forward, you can commence a trial with her and let her burn at the stake. You have to ask Alphonso DiCerbio about them first.

I tried my luck with Thief and also got promotional quest to find relic by Baron request.
I think the only difference is who will give you new title after finding relic - Vallejan? for Priest, Baron for Thief and Edmond for Paladin.
