I was shocked that there are no complete achievement guide for this game so i decided to create one from the informations i collected or explored for my own walkthrough. Unfortunately i wasnt able to find complete, detailed information about achievements. It is only possible to find details for single achievement but it is quite time consuming to find for all so i hope now a complete guide will help the life of those who planing to perfect the game.

Class/guild quests and achievements might be missable if you travel to next city without solving the events beforehand.

Dont be afraid to create millions of saves, leave the main progresses for last in each act so you can change the outcomes and progress differently:-)

Always reserve as many skill points as many you can, loading sometimes easier to adjust skills is better than stuck on the wrongly increased skills. If you fail to get something you increase required skills and decide if it worth it or not.

Please understand that you cant increase all skills and be a god in all kind of areas. This is why this game is hard, very hard, you need to do with your character what it's talents allow you, but quests, events most of the time allows you to handle story differently.

Please respect my work and use thumbs up on the guide if it helped to you to get an achievement.

Please consider to follow my curator group if you like achievements and curious about completion times, how difficult to perfect a game, DLCs or MP required for achievements or not and some other useful, achievementrelated information:

If Esbenus survived Act1 (bandit at bandit camp) then it's possible you cant get this one, please confirm if its not true.

The Right Thing

The One God

Ascend. Iam not 100% sure its only praetor exlsuvie but as i experienced only prateros can accompany Meru to the ritual chamber of Al-Akia. You can start other class but you need to be praetor for Ganezzar for sure. Steps to get this achievement:
-you need to get the surgical kit from Library of Saross, easiest for all this walkthrough is to turn to praetor of Aurelian and while going for Deal with the Devil achievement, right after it, you will be at Harrans pass where you see a dead body, it's Bass.

"Good Morrow To You, Magistrate!"

Outmaneuver your opponents and make Strabos the new magistratus of Maadoran. This is the best ending for your commercium activities in Maandoran but unlike the game of thrones this is missable even if you follow the quest. You need to persuade Serenas to announce a lowborn, aka your master Strabos the new magister. Usual stats required what a merchant playthrough need anyway: charisma, persuasion/streetwise. The way i got at Serenas is that i mentioned the magistrate position is a job, require day and night work and they should know nobleborns, they wont do that.

The Opium of the People

Corporate Interests

Complete the Merchants Guild's questline in Ganezzar as per Strabos' orders. Make Pallus to support House Aurelias with the Imperial Legion.

Once a Traitor…

You have a dangerous habit of betraying your masters. There are information on net that it's doable with other classes but i managed to do it only this method:

Start as merchant or join merchant guild, make sure you have 8 int starter stat, you need to be silver tongued heavy statwise, there will be 1 fight tho, but imperial guards can win the battle your main task just to survive.
Do the raider camp and aurelian outpost quests, well, make raiders attack the post.
After this you should be able to pledge loyalty to house Daratan while speaking with the lord.
Now progress on commercium quests until you visited boatmen. Dont try to make lord avoid the need of proofs.
Tell to commercium you need to collect proofs, but dont forge it by yourself.
Go to the Imperial Guard Barrack and offer your services to Carrinas.
Survive the Battle
Take the documents back to Linos for heavy loyalty loss.
at this point you can save which is recommended as you could make other achievements too like Kingmaker.
now go to daratan compund and dont insult antidas. with persuation and trade skillcheck twice you can offer him to be Emperor.
Now when talking to Carrinas after a persuation and trade skillcheck you can use your 8INT to make Carrinas to promote Antidas to Emperor after 2 INT skillcheck, if one succeded or not going for second you can get diplomat achievemet.
Once passed both INT skillcheck, select the: "This is a very valuable document. Take it and get out of Teron as fast as you can." to get this achievement
reload and choose the Take the document to Antidas instead for the Kingmaker achievement.

Personal Magnetism

Convince Centurion Flavius to introduce you to Lord Antidas. Iam not sure it's thief guild exclusive, but Flavius was mentioned only one of their Teron quest. Approach the castle and choise the following chat options:
-look for an alternative way in
-(impersonate) Pretend to be a guard and go through the guard entrance (it was failed even with a 6 skill but you need to fail it anyway)
-(persuation+streetwise) Clicked through but the sentence was about looking for a job and you want to be a guard.
-Then i would like to apply.
-(persuasion) Look, i dont want....
-5*single choice
-(persuasion) Iam not a fighting man...
-(persuasion+charisma) Like i said....
