I too prefer the latter.

Damage reduction 10/cold iron?
Challenge Rating: 8? The DR and SLAs are worth at least a point over the phasm, eh? 1 higher than that for the social version?
Advancement: x. Phasm has 15–21 HD (Huge); 22–45 HD (Gargantuan), but I don't really feel really big phoukas make sense. Maybe 15-30 HD (Large)?
Other than deciding upon a name for the "social" phouka, I believe we're done here.
Hrmph. Maybe just go 20th level on the CL.
There's still a social phouka hanging out with the friendly phoukas.![]()
I'm not sure there's any need to go above CL 20, is there? That's pretty unusual for a stat block (even among angels and fiends of more than 20 HD), though you could argue that some of the advancement rules kind of imply that.
