An eidolon’s abilities are determined by the summoner’s level and by the choices made using its evolution pool. Table: Eidolon Base Statistics determines many of the base statistics of the eidolon. Each eidolon possesses a base form that modifies these base statistics. Eidolons are outsiders for the purpose of determining which spells affect them.

This is the character’s summoner level.
HD
This is the total number of 10-sided (d10) Hit Dice the eidolon possesses, each of which gains a Constitution modifier, as normal.
BAB
This is the eidolon’s base attack bonus. An eidolon’s base attack bonus is equal to its Hit Dice. Eidolons do not gain additional attacks using their natural weapons for a high base attack bonus.
Good/Bad Saves
These are the eidolon’s base saving throw bonuses. An eidolon possesses two good saving throws and one bad saving throw, determined by the creature’s base form.
Skills
This lists the eidolon’s total skill ranks. An eidolon can assign skill ranks to any skill, but it must possess the appropriate appendages to use some skills. Eidolons with Intelligence scores above the base value modify these totals as normal (an eidolon receives a number of skill ranks equal to 6 + its Intelligence modifier per HD). An eidolon cannot have more ranks in a skill than it has Hit Dice. Eidolon skill ranks are set once chosen, even if the creature changes when the summoner gains a new level.
Eidolon Skills
The following skills are class skills for eidolons:
Bluff (Cha), Craft (Int), Knowledge (planes) (Int), Perception (Wis), Sense Motive (Wis), and Stealth (Dex).
In addition, at 1st level, the summoner can choose 4 additional skills to be class skills for his eidolon. Note that eidolons with a fly speed receive Fly (Dex) as a free class skill, even if they do not gain a fly speed until a later level.
Feats
This is the total number of feats possessed by an eidolon. Eidolons can select any feat that they qualify for, but they must possess the appropriate appendages to use some feats. Eidolon feats are set once chosen, even if the creature changes when the summoner gains a new level. If, due to changes, the eidolon no longer qualifies for a feat, the feat has no effect until the eidolon once again qualifies for the feat.
Armor Bonus
The number noted here is the eidolon’s base total armor bonus. This bonus may be split between an armor bonus and a natural armor bonus, as decided by the summoner. This number is modified by the eidolon’s base form and some options available through its evolution pool. An eidolon cannot wear armor of any kind, as the armor interferes with the summoner’s connection to the eidolon.
Str/Dex Bonus
Add this modifier to the eidolon’s Strength and Dexterity scores, as determined by its base form. Some options available through the eidolon’s evolution pool might modify these scores.
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).
Max. Attacks
This indicates the maximum number of natural attacks that the eidolon is allowed to possess at the given level. If the eidolon is at its maximum, it cannot take evolutions that grant additional natural attacks. This does not include attacks made with weapons.
Special
This includes a number of abilities gained by all eidolons as they increase in power. Each of these bonuses is described below.
Link (Ex)
A summoner and his eidolon share a mental link allows for communication across any distance (as long as they are on the same plane). This communication is a free action, allowing the summoner to give orders to his eidolon at any time. In addition, magic items interfere with the summoner’s connection to his eidolon. As a result, the summoner and his eidolon share magic item slots. For example, if the summoner is wearing a ring, his eidolon can wear no more than one ring. In case of a conf lict, the items worn by the summoner remain active, and those used by the eidolon become dormant. The eidolon must possess the appropriate appendages to utilize a magic item.
Share Spells (Ex)
The summoner may cast a spell with a target of “you” on his eidolon (as a spell with a range of touch) instead of on himself. A summoner may cast spells on his eidolon even if the spells normally do not affect creatures of the eidolon’s type (outsider). Spells cast in this way must come from the summoner spell list.
This ability does not allow the eidolon to share abilities that are not spells, even if they function like spells.
Evasion (Ex)
If an eidolon is subjected to an attack that normally allows a Reflex save for half damage, it takes no damage if it makes a successful saving throw.
Ability Score Increase (Ex)
The eidolon adds +1 to one of its ability scores
Devotion (Ex)
An eidolon gains a +4 morale bonus on Will saves against enchantment spells and effects.
Multiattack
An eidolon gains Multiattack as a bonus feat if it has 3 or more natural attacks and does not already have that feat. If it does not have the requisite 3 or more natural attacks (or it is reduced to less than 3 attacks), the eidolon instead gains a second attack with one of its natural weapons, albeit at a –5 penalty. If the eidolon later gains 3 or more natural attacks, it loses this additional attack and instead gains Multiattack.
Improved Evasion (Ex)
When subjected to an attack that allows a Reflex saving throw for half damage, an eidolon takes no damage if it makes a successful saving throw and only half damage if the saving throw fails.
Each eidolon has one of three (four if using Ultimate Magic) base forms that determines its starting size, speed, AC, attacks, and ability scores. All natural attacks are made using the eidolon’s full base attack bonus unless otherwise noted (such as in the case of secondary attacks). Eidolon attacks add the eidolon’s Strength modifier to the damage roll, unless it is its only attack, in which case it adds 1-1/2 times its Strength modifier. These base forms also note any free evolutions that base form possesses. The bonuses from these free evolutions are already factored into the starting statistics. Alternatively, any one of these base forms can be used to make a Small eidolon. If the eidolon is Small, it gains a +2 bonus to its Dexterity score. It also takes a –4 penalty to its Strength and a –2 penalty to its Constitution. It also gains a +1 size bonus to its AC and attack rolls, a –1 penalty to its CMB and CMD scores, a +2 bonus on its Fly skill checks, and a +4 bonus on its Stealth skill checks. Reduce the damage of all of its attacks by one step (1d6 becomes 1d4, 1d4 becomes 1d3). If this choice is made, the eidolon can be made Medium whenever the summoner can change the eidolon’s evolution pool (which causes it to lose these modifiers for being Small).
Ultimate Magic introduced a fourth base form: aquatic. The aquatic base form follows all of the normal rules for base forms.

Each eidolon receives a number of evolution points that can be spent to give the eidolon new abilities, powers, and other upgrades. These abilities, called evolutions, can be changed whenever the summoner gains a new level, but they are otherwise set. Some evolutions require that the eidolon have a specific base form or the summoner be of a specific level before they can be chosen. A number of evolutions grant the eidolon additional natural attacks. Natural attacks listed as primary are made using the eidolon’s full base attack bonus and add the eidolon’s Strength modifier on damage rolls. Natural attacks listed as secondary are made using the eidolon’s base attack bonus – 5 and add 1/2 the eidolon’s Strength modifier on damage rolls (if positive). If the eidolon only has a single natural attack, the attack is made using its full base attack bonus and it adds 1-1/2 times its Strength modifier on damage rolls made with that attack, regardless of the attack’s type.
Evolutions are grouped by their cost in evolution points. Evolution points cannot be saved. All of the points must be spent whenever the summoner gains a level. Unless otherwise noted, each evolution can only be selected once.
The following evolutions cost 1 point from the eidolon’s evolution pool.
Basic Magic (Sp)
An eidolon learns to cast a basic spell as a spell-like ability. Select one spell from the following list: acid splash, dancing lights, daze, detect magic, flare, ghost sound, light, mage hand, ray of frost, stabilize, or touch of fatigue. This spell can be cast once per day as a spell-like ability. At 4th level, this spell can be cast three times per day by spending 2 additional evolution points. The caster level for this evolution is equal to the eidolon’s Hit Dice. The save DC for this spell is 10 + the eidolon’s Charisma modifier. The eidolon must have a Charisma score of at least 10 to take this evolution. This evolution can be selected more than once. Each time an eidolon selects this evolution, it applies to a new spell.
