Many evolutions have a specific limit as to how many times you can take them. How does that work when putting the evolutions onto the summoner.
Say, for example, I can take the Improved Natural Armor evolution 4 times. Can I put it 4 times EACH on the eidolon and the summoner? Or do I have to split the 4 selections BETWEEN the summoner and eidolon?
This is especially important for evolutions that can only be taken once. If I give my eidolon a spell-like ability, does that mean that my summoner can no longer ALSO select that option for himself?
