The following evolutions cost 1 point from the eidolon's evolution pool. Bite (Ex) : The eidolon's maw is full of razor-sharp teeth, giving it a bite attack. This attack is a primary attack. The bite deals 1d6 points of damage (1d8 if Large, 2d6 if Huge). If the eidolon already has a bite attack, this evolution allows it to deal 1-1/2 times its Strength modifier on damage rolls made with its bite. Requirements : Agathion, daemon, demon, devil, div, elemental, protean, or psychopomp subtype. Claws (Ex) : The eidolon has a pair of vicious claws at the ends of its limbs, giving it two claw attacks. These attacks are primary attacks. The claws deal 1d4 points of damage (1d6 if Large, 1d8 if Huge). The eidolon must have the limbs evolution to take this evolution. This evolution can be selected more than once, up to the number of limbs evolutions the eidolon possesses. This evolution can be applied to any number of limbs (arms) evolutions, but no more than one limbs (legs) evolution. Requirements : Agathion, daemon, demon, devil, div, elemental, protean, or psychopomp subtype. Climb (Ex) : The eidolon becomes a skilled climber, gaining a climb speed equal to its base speed. This evolution can be selected more than once. Each additional time it is selected, increase the eidolon's climb speed by 20 feet. Gills (Ex) : The eidolon has gills and can breathe underwater indefinitely. Improved Damage (Ex) : One of the eidolon's natural attacks is particularly deadly. Select one natural attack form and increase the damage die by one step. This evolution can be selected more than once. Its effects do not stack. Each time the eidolon selects this evolution, it applies to a different natural attack. Improved Natural Armor (Ex) : The eidolon's hide grows thick fur, rigid scales, or bony plates, giving it a +2 bonus to its natural armor. This evolution can be taken once, plus one additional time for every 5 levels the summoner possesses. Each additional time it's taken, the bonus increases by 2. Magic Attacks (Su) : The eidolon is infused with magic, allowing it to treat all of its natural attacks as if they were magic for the purpose of overcoming damage reduction. If the summoner is 10th level or higher, all of the eidolon's natural attacks are treated as the alignment of the eidolon for the purpose of overcoming damage reduction.
Mount (Ex) : The eidolon is properly skilled and formed to serve as a combat-trained
mount. The eidolon must be at least one size category larger than its rider. Requirements : Daemon, demon, devil, elemental, or protean subtype; quadruped or serpentine base form. Pincers (Ex) : An eidolon grows large pincers at the ends of one pair of its limbs, giving it two pincer attacks. These attacks are secondary attacks. The pincers deal 1d6 points of damage (1d8 if Large, 2d6 if Huge). Eidolons with the grab evolution linked to their pincers gain a +2 bonus on combat maneuver checks to grapple. The eidolon must have the limbs (arms) evolution to take this evolution. Alternatively, the eidolon can replace the claws from its base form with pincers (this still costs 1 evolution point). This evolution can be selected more than once, up to the number of limbs (arms) evolutions the eidolon possesses. Requirements : Agathion, daemon, demon, devil, div, elemental, protean, or psychopomp subtype. Pull (Ex) : The eidolon gains the ability to pull creatures closer with a successful attack. Select one type of natural attack. Whenever the eidolon makes a successful attack of the selected type, it can attempt a free combat maneuver check. If the eidolon succeeds at this check, it pulls the target of the attack 5 feet closer to it. This ability works only on creatures of a size category equal to or smaller than the eidolon. Creatures pulled in this way do not provoke attacks of opportunity. This evolution can be selected more than once. Its effects do not stack. Each time an eidolon selects this evolution, it applies to a different natural attack. Requirements : Reach of 10 feet or more. Push (Ex) : The eidolon gains the ability to push creatures away with a successful attack. Select one type of natural attack. Whenever the eidolon makes a successful attack of the selected type, it can attempt a free combat maneuver check. If the eidolon succeeds at this check, it pushes the target of the attack 5 feet directly away from it. This ability works only on creatures of a size category equal to or smaller than the eidolon. Creatures pushed in this way do not provoke attacks of opportunity. This evolution can be selected more than once. Its effects do not stack. Each time an eidolon selects this evolution, it applies to a different natural attack. Reach (Ex) : One of the eidolon's attacks is capable of striking foes at a distance. Select one attack. The eidolon's reach with that attack increases by 5 feet.
Resistance (Ex) : The eidolon's form takes on a resiliency to one particular energy type, which is usually reflected in its physical body (ashen hide for fire, icy breath for cold, and so on). Select one energy type (acid, cold, electricity, fire, or sonic). The eidolon gains
resistance 5 against that energy type. This
resistance increases by 5 for every 5 levels the summoner possesses, to a maximum of 15 at 10th level. This evolution can be selected more than once. Its effects do not stack. Each time the eidolon selects this evolution, it applies to a different energy type. Scent (Ex) : The eidolon's sense of smell becomes quite acute. The eidolon gains the scent special quality, allowing it to detect opponents within 30 feet by sense of smell. If the opponent is upwind, the range increases to 60 feet; if the opponent is downwind, the range drops to 15 feet. Strong scents can be detected at twice the normal range. Scent does not allow the eidolon to precisely locate the creature, only to detect its presence. It can detect the direction as a move action. The eidolon can pinpoint the creature's location if it is within 5 feet. The eidolon can use scent to track creatures. Skilled (Ex) : The eidolon becomes especially adept at a specific skill, gaining a +8 racial bonus on that skill. This evolution can be selected more than once. Its effects do not stack. Each time the eidolon selects this evolution, it applies to a different skill. Slam (Ex) : The eidolon can deliver a devastating slam attack. This attack is a primary attack. The slam deals 1d8 points of damage (2d6 if Large, 2d8 if Huge). The eidolon must have the limbs (arms) evolution to take this evolution. Alternatively, the eidolon can replace the claws from its base form with this slam attack (this still costs 1 evolution point). This evolution can be selected more than once, up to the number of the eidolon's limbs (arms) evolutions. Sting (Ex) : The eidolon possesses a long, barbed stinger at the end of its tail, granting it a sting attack. This attack is a primary attack. The sting deals 1d4 points of damage (1d6 if Large, 1d8 if Huge). This evolution can be selected more than once, up to the number of tail evolutions the eidolon possesses. Requirements : Agathion, daemon, demon, devil, div, elemental, protean, or psychopomp subtype; tail evolution. Swim (Ex) : The eidolon gains webbed hands, webbed feet, or powerful flippers, giving it a swim speed equal to its base speed. This evolution does not give the eidolon the ability to breathe underwater. This evolution can be selected more than once. Each additional time it is selected, increase the eidolon's swim speed by 20 feet. Tail (Ex) : The eidolon grows a long, powerful tail. This grants it a +2 racial bonus on Acrobatics checks to balance on a surface. This evolution can be selected more than once. Requirements : Agathion, daemon, demon, devil, div, elemental, protean, or psychopomp subtype. Tail Slap (Ex) : The eidolon can use its tail to bash nearby foes, granting it a tail slap attack. This attack is a secondary attack. The tail slap deals 1d6 points of damage (1d8 if Large, 2d6 if Huge). This evolution can be selected more than once, up to the number of tail evolutions the eidolon possesses. Requirements : Agathion, daemon, demon, devil, div, elemental, protean, or psychopomp subtype; tail evolution. Tentacle (Ex) : The eidolon possesses a long, sinuous tentacle, granting it a tentacle attack. This attack is a secondary attack. The tentacle attack deals 1d4 points of damage (1d6 if Large, 1d8 if Huge). This evolution can be selected more than once. Requirements : Daemon, demon, or protean subtype. Wing Buffet (Ex) : The eidolon learns to use its wings to batter foes, granting it two wing buffet attacks. These attacks are secondary attacks.
