I started with somewhere around 180,000 PK points.

The character started at level 28. Now it’s level 10. All I did was log in with a bot and set it to stand around in town, respawn, and then simply do nothing until the character dies again. It only took around 7 hours, though for about one of those hours I had it set to walk outside town where I had a wizard standing by to nuke me, so that may have sped things up just a little bit.
