One of my players wants to be a synthesis summoner, but how does the size increase evolution work? If he takes the evolution that makes his eidolon Large, does he become large too?
On one hand, it seems that if he's "wearing" his eidolon, he would grow along with it. However, being a synthesist, it says your *eidolon* conforms to *you*. I mean, the thing basically becomes your armor, and you can't wear armor that's too big for you...
How would anyone else DM this?
(We're getting ready to do Emerald Spire, so being Large would be a pretty big inconvenience, hence why we need to know.)
