Yes, it will be, but we should get on with it! I'll take a look and post about it as soon as I get a chance...
The basic concepts are pretty simple.
An ovinaur can eat the sins of a deceased sapient, which are measured by the dead creature's levels (Hit Dice). This earns the ovinaur XP, but results in the ovinaur suffering randomly determined afflictions that cause Constitution or Charisma penalties. The dice rolled to decide the affliction depend on the ratio of the ovinaur's hit dice to the total number of sin-levels eaten, with more dice for a higher ratio. Once every full moon an ovinaur can attempt to cleanse its sins by making a series of Wisdom checks, each consecutive success lowers the sin-ratio by one ranking.
The benefits of sin-eating is that a creature whose sins have been eaten can't return as an undead. Unfortunately, this means that an ovinaur whose dies before it is able to cleanse the sins it has eaten is liable to return as an undead. An ovinaur cannot eat the sin-levels of another ovinaur.
