Peacemaking

[Miri]

I know that the taming system here has been tweaked somewhat with the skill requirements for certain critters having been raised, but is the same true for Peacemaking and, if so, to what degree?

My tamer has 120 real-skill in both musicianship and peacemaking, she's not using any jewelry to augment it, and yet she's still not able to use peacemaking on certain creatures. It's not that she fails an attempt, it's that her skill is apparently not high enough to even try.

Am I missing something? Or, for whatever reason, have the hiryu (normal, not the lesser or ancient) and rune beetle been set as essentially un-peace-able?

Some are indeed bard immune I believe. I think rune beetles are and not sure of the rest. But, if you can't even attempt at 120, then likely they are bard immune.
