Past Mistakes is a Quest in Divinity: Original Sin II. A powerful sourcerer is being held captive, but it may not be long before he escapes his prison. Will you be able to stop him before he does?
- Defeat Karon, the Mistake.
The Mistake is held as a prisoner in a Magister prison, and you can reach there through the sewers.
The easiest and fastest way into the sewers is to follow the dead Magisters. First, cast Spirit Vision in the Magister's Barracks and speak to Wainslow as shown in the picture below. Agree to help him find Bannet, and find Bannet's corpse near the sewer, shown in the second picture. Cast Spirit Vision again and speak to Bannet's spirit, then enter the sewer (NOTE : The book "Report Of The Toyseller" may be found on Brannt's body instead of on the desk in the 2nd secret room under the Barrack's kitchen).
Head to the south and you will soon see his cage as in the picture below. There is a locked iron grate here which you can use to get to where he is, but you'll still have to teleport down. When you reach the boy's cage, cast Spirit Vision and you will see dead Seekers trying to seal the Mistake forever. You can leave them be or break the boy's cage, but if you break his cage, be prepared for a hard fight.
In order to break his cage, you will need to light the 5 brasiers. The seekers will actively blow out the fire if you try to light the brasiers, so a spell like Fireball may be required. (You can also use lock-picks, or teleports or some other tricks.)
In any case, once all 5 braziers have been lit, he will be free and transform into a powerful Godwoken mage. Another way to free him is to use Source Vampirism on him. He will break free and remark on how you attacked a child. After a brief conversation, he will attack you, along with 4 other undead minions. Make him realize his mistake. Note that he can resurrect his undead minions if they die, and perform source vampirism on your characters to steal their source. The undead minions give no XP when killed, but killing Karon will give 188,650XP. Once he is killed, you will receive another 96,950XP and the quest will be complete. You can cast Spirit Vision at this point and talk to his spirit to find out why he's so bitter in the first place, if you so choose.
Note that if you leave the area without killing the mistake, later when you revisit the place, you will find that he's already escaped, thanks to the foolishness of the Paladins. You can still light the braziers to summon and fight him though, but this time, you won't be facing any of his minions. Killing him will grant the same XP as above. You could also travel to Linder Kemm's mansion to find him slaughtering citizens. (NOTE: If you use the waypoint to Kemm's gardens, you will not initiate this fight. You must enter through town.)
Loot the Level 19 crossbow Vord Emver on one of his minions.
Update: In the Definitive Edition, Karon will escape from his cage (and remove all of the Seeker spirits except Wrenley) after you leave (so he will be missing when you return). Karon appears right after you pass the Path of Blood instead. However, at that point, you should generally be strong enough to defeat him without much issues.
- 188,650XP for killing Karon.
- 96,950XP upon completion of this quest.
- 1 Talent Point if you defeat him in the Lucian’s Crypt (Persuasion check, Definitive Edition)
