Dark Judge:
Many sinners think they can wash their sins away easily. We, Dark Judges, don't think so, and don't allow to be so. That's why we've changed redemption requirements.
Now only characters of Lv. 85 and higher who paid 10,000,000 adena and got Scroll: Summon Sin Eater can receive absolution. Those who have the scroll can accept a special quest. Complete it - and we'll forgive a part of your sins as a reward.
Keep in mind that you can buy a Scroll: Summon Sin Eater and complete the quest only once a day.
