Spell-Like Abilities: Pegasi can detect good and detect evil at will within a 60-yard radius, as the spells cast by a 5th-level sorcerer.

Plant: Immune to mind-influencing effects, poison, sleep, paralysis, stunning, and polymorphing. Not subject to critical hits.

Improved Invisibility (Su): This ability is constant, allowing the phantom fungus to remain invisible even when attacking. This works just like improved invisibility cast by a 12th-level sorcerer, and lasts as long as the phantom fungus is alive. This ability is not subject to the invisibility purge spell. Once killed, a phantom fungus becomes visible after 1 minute.

Ethereal Jaunt (Su): A phase spider can shift from the Ethereal to the Material Plane as a free action, and shift back again as a move-equivalent action (or during a move-equivalent action). The ability is otherwise identical with ethereal jaunt cast by a 15th-level sorcerer.

Poison (Ex): Bite, Fortitude save (DC 15); initial and secondary damage 2d6 temporary Constitution.

Amorphous (Ex): A phasm in its natural form is immune to poison, sleep, paralysis, stun, and polymorph. It is not subject to critical hits and, having no clear front or back, cannot be flanked.

Alternate Form (Su): Phasms can assume the form of any corporeal creature or object from Diminutive to Large size as a standard action. This ability is otherwise similar to shapechange as cast by a 20th-level sorcerer.

Telepathy (Su): Phasms can communicate telepathically with any creature within 100 feet that has a language.

Tremorsense (Ex): A phasm can automatically sense the location of anything within 60 feet that is in contact with the ground, so long as it is touching the ground itself.

Poison (Ex): Sting, Fortitude save (DC 12); initial damage sleep for 1 minute, secondary damage sleep for 1d3 days.

See Invisibility (Ex): Pseudodragons continuously see invisibility as the spell, with a range of 60 feet.

Telepathy (Su): Pseudodragons can communicate telepathically with creatures that speak Common or Sylvan, provided they are within 60 feet.

Immunities (Ex): Pseudodragons are immune to sleep and paralysis effects.

Improved Grab (Ex): To use this ability, the purple worm must hit with its bite attack. If it gets a hold, it automatically deals bite damage and can attempt to swallow the foe.

Swallow Whole (Ex): A purple worm can try to swallow a grabbed opponent of Large or smaller size by making a successful grapple check. Once inside, the opponent takes 2d8+12 points of crushing damage plus 1d8 points of acid damage per round from the worm's gizzard. A swallowed creature can climb out of the gizzard with a successful grapple check. This returns it to the worm's maw, where another successful grapple check is needed to get free. A swallowed creature can also cut its way out by using claws or a Small or Tiny slashing weapon to deal 25 points of damage to the gizzard (AC 20). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out. The worm's interior can hold two Large, four Small, eight Tiny, sixteen Diminutive, or thirty-two Fine or smaller opponents.

Poison (Ex): Sting, Fortitude save (DC 24); initial damage 1d6 temporary Strength, secondary damage 2d6 temporary Strength.

Tremorsense (Ex): A purple worm can automatically sense the location of anything within 60 feet that is in contact with the ground.

Light (Sp): Aasimars can use light once per day as cast by a sorcerer of 1st level or their character level, whichever is higher.

Darkness (Sp): Tieflings can use darkness once per day as cast by a sorcerer of 1st level or their character level, whichever is higher.
