So if you have a player who is playing a large race and starts at level 1 Summoner, Synthesist Archtype can he fuse with his eidolon? And what if someone/yourself casts Enlarge Person on you. The Rule(The eidolon must be at least the same size as the synthesist.)
Here are the options/questions i can think of.
1) Does the eidolon automatically start the same size as the race?
2) Does he wait till level 2 to have 4 points in the Evolution Pool and ignore the level 8 requirement?
3) Does he wait till level 8 for the Large Evolution requirement?
Scenario Question- A player is a werebear synthesist, when he is in hybrid form he increases in size. (This greatly differs from the spell Enlarge Person as you could say the eidolon magically increases, but again the key is COULD SAY.) What are the mechanical rules for the eidolon to fuse with the synthesist?
