WanderingPriest Mod Question

[shatner]

I am trying to make it so a mage for MA Jomon loses one point in all paths when it is outside its home province. This is already an effect that works on Ujigami and Yama-no-kami; I vaguely remember from the now defuct wiki that this tag was called WanderingPriest.

Anyway, I can't find a way to directly add this tag to the mage in question, so I've instead used copystat on the Ujigami to get it. However, that brings with it a couple of undesired traits such as a standard (I can reduce the standard to 1, but it's still there), magic being (can't figure out how to get that removed), need not eat (ditto), and ethereal. All of those are small potatoes that can be ignored except for ethereal; that's a big deal and having that on a recruit-anywhere mage is no good.

So, is there a way for me to directly add this wanderingpriest effect? If not, is there a way to remove ethereal from a unit (and bonus points if you tell me how to remove magicbeing, neednoteat, and standard)? If not, is there a better unit than the Ujigami that I can copy the stats of to get this effect?

Many, many thinks in advance for any help.
