Summoner questions, PF1E

[Edward McGee]

Evolution Pool: The value given in this column is the total number of points in the eidolon's evolution pool. Points from this pool can be spent on a wide variety of modifications and upgrades that add new abilities, attacks, and powers to the eidolon. Whenever the summoner gains a level, the number in this pool increases and the summoner can spend these points to change the abilities of the eidolon. These choices are not set. The summoner can change them whenever he gains a level (and through the transmogrify spell).

So for example at level 4 your eidolon has an evolution pool of of 3. It can have 3 points total worth of evolutions. At level 5 that pool goes up to 4 points. You can add a 1 point evolution or it can lose it's current abilities and you can spend those 4 points some other way.

From what I hear the Unchained eidolon is not as good in combat as the old version but they can make very good skill monkeys.
