Ah, ok. Maybe not as OP as I thought, but would still be quite useful for specific scenarios (Xfer VIT to a low VIT HW for example).
If someone knows if the 256 can be "broken" via Apostola, that would be awesome.
That will be the first thing I'll check when I get my servant, I have a bishop with apostolia and 279 int, it will be easy to check if my maxMP goes up
I've tested this, Using stat release on the receiving character to increase the maximum stat, does NOT affect the maximum stat from soul connect. Casting on 282 int bishop with apostolia did not increase int on the bishop. Max stat will be limited to 256
