For players who like to drain noobs in PK on the spot, the developers have come up with the perfect quest to wash off karma. If you are looking for a way to lower your PK, then you are in the right place.
This quest is suitable for both Interlude and High Five, so chronicles don't matter.
The PC collar is also useful for spoilers, as it allows you to stop the accumulation of experience - IMP absorbs 100% of the character's experience.
1. The PC laundering quest in Interlude is called Repent Your Sins and starts at the Black Judge in Hardin's Academy .
2. Use Scroll of Escape , go to Oren, then to Ivory Tower . On the 3rd floor we find Joan .
3. She tasks you with killing Trisalim Tarantula and bringing 3 quest items.
4. Return to Joan , then go to Hardin's Academy to Black Judge , who instructs you to deliver the letter to the blacksmith Pushkin in Giran .
You also need to collect the resources required to create the collar 
needed for the PC Laundering quest.
2 Adamantium Ingots
1 Blacksmith's blank 
10 Cox 
5 Steel 
10 silver bars 
5. We get the collar from Pushkin .
We take it to the Black Judge and get it into our inventory.
This completes the quest to remove the PC.
A few rules on how to properly clean your PC in Lineage 2:
- Do not change subclass if the collar is activated (you started leveling, but have not yet completed the quest), otherwise it will disappear.
- Upgrade only 1 level - if you upgrade more, only 1 PC will be removed.
- Feed your pet Food For Wolves .
- If you upgrade the Devil to level 1 , then 1 to 10 PCs will be removed - randomly.
