this is a post from ladynico
"There is no increased skill loss on being peace or discord tamed. There is no stat (str/dex/int)loss at all for para/peace/discord taming.
Only paralyse taming brings with it the extra 4% loss of skill and even that only negatively affects those critters whose skills may exceed 100.
When I get tired of walking around in circles, I regularly para-tame cu sidhes since all skills reach a maximum of 100 and they can all be retrained to their 100 max skills.
I would not, however, consider para-taming reptalons, fire steeds, hiryus, rune beetles, or greater dragons, etc., whose skills can exceed 100. Discord or peace tame them? Sure, no extra loss for either. "
that being said there ending stats are figured from the stats they start with the exception to this is if you paralyze them
there is more info if you use the search method in the tamer forum
hope this helps
