ok, i checked the quest "Repent Your Sins" and it appears that the black judge removes PK's randomly from 1 to 10.
wat i want to know is if there's something that influenciates this number, because i already lvl up the sin eater 2 lvls, although it only needs 1, but its great for farming , but i thought that maybe if u lvl it p more than 1 lvl the removed PK points will be less, or more, dunno, is there anything that can modify this things?

no matter of the lvl of the pet
it is random even if you give him 50 more levels.

i dont think its random
1 lvl -- 3 pk points
2 lvls -- 7 pk points
3 lvls -- 10 pk points
that what i get remove .... and other clan mates too but it could be ur lvl whats make random difference

offie or private ?
on offie it's random, a clan mate SH tried it
1 more lvl =>4 pk
2 more lvl =>2 pk
another 2 more lvl =>3 pk

he had 26 pk before starting the quest 1st

on private server .. dexternet (4x and srry no comercial here) maybe u are right dunno on offi how things are

hmmm, i lvl him 3 lvls and i got 5 removed
