Evolutions

Each eidolon receives a number of evolutions based on the ranks an arcanist has in summoning. These ranks give the eidolon new abilities, powers, and other upgrades. These abilities, called evolutions, can be changed whenever the arcanist gains a new rank in summoning, but they are otherwise set. A number of evolutions grant the eidolon additional natural attacks.

Evolutions are grouped by their evolution rank. Unless otherwise noted, each evolution can only be selected once.

At first rank an eidolon can have 3 bonus 1st tier evolutions.

At second rank an eidolon can have one extra 1 tier evolution and a 2 tier evolution.

At third rank an eidolon can have an extra 1 tier evolution, an extra 2 tier evolution and a 3 tier evolution.

At fourth rank an eidolon can have an extra 1 tier evolution, an extra 2 tier evolution and an extra 3 tier evolution as well as one 4 tier evolution.

At fifth rank an eidolon can have an extra evolution in all four tiers. An eidolon should have seven 1 tier evolutions, four 2 tier evolutions, three 3 tier evolutions and two 4 tier evolutions.
