Specifically, this clause:
The spirit gains 3 points of influence over his body, to a maximum of 6 points. Since he is his own possessing spirit, he doesn’t lose control at 5 or more points of influence, though he still suffers the legend’s influence penalty as normal at 3 or more points of influence.
I get that the medium (which I'll refer to as X, meaning the inhabiting spirit of the character) having a higher influence over his own body (spiritless without assistance, henceforth Y) is good and that he invites a legend (Z) in there with him, I'm just a little fuzzy on what else happens. Looking at it as-is, it reads to me like he (X) and the spirit (Z) have two different influence totals, but there is no clarification in-text. If they have two different influence totals, who gains the 3 points of influence when he channels a legendary spirit? Was the intention of this to make the medium immediately suffer the influence penalty from the legendary spirit, because that kind of looks like what it means if the legend is the one that gets the 3 influence when it's channeled.
So...X is the only one who gains and loses influence over his body? Do I track the legend's influence separately, but suffer no penalties when it has 5 or more influence over the body? Does "The spirit" (at the beginning of the quote) refer to the Medium's spirit, X, or the spirit of the legend he's channeling, Z?
Basically hoping for writer confirmation one way or the other on this-I'm kind of turned around.
