A mesmerist casts psychic spells drawn from the mesmerist spell list. He can cast any spell he knows without preparing it ahead of time. To learn or cast a spell, a mesmerist must have a Charisma score equal to at least 10 + the spell’s level. The saving throw DC against a mesmerist’s spell is 10 + the spell’s level + the mesmerist’s Charisma modifier.

Like other spellcasters, a mesmerist can cast only a certain number of spells of each spell level per day. His base daily spell allotment is given on Table: Mesmerist. In addition, he receives bonus spells per day if he has a high Charisma score.

The mesmerist’s selection of spells is limited. A mesmerist begins play knowing four 0-level spells and two 1st-level spells of the mesmerist’s choice. At each new mesmerist level, he learns one or more new spells, as indicated on Table: Mesmerist Spells Known.

Unlike a mesmerist’s spells per day, the number of spells a mesmerist knows isn’t affected by his Charisma score; The numbers on the table are fixed.

At 5th level and every 3 levels thereafter, a mesmerist can choose to learn a new spell in place of one he already knows.

In effect, the mesmerist loses the old spell in exchange for the new one. The new spell’s level must be the same as that of the spell being exchanged, and it must be at least 1 level lower than the highest-level mesmerist spell the mesmerist can cast. A mesmerist can swap only a single spell at any given level, and must choose whether or not to swap the spell at the same time that he gains new spells known for the level.

A mesmerist need not prepare his spells in advance. He can cast any mesmerist spell he knows at any time, assuming he has not yet used up his allotment of spells per day for the spell’s level.

Knacks: Mesmerists learn a number of knacks, or 0-level spells. These spells are cast like any other spells, but they do not consume any slots and can be used again. Knacks cast using other spell slots, due to metamagic feats, for example, consume spell slots as normal.

A mesmerist can create hypnotic bonds with his allies, implanting magical suggestions in their minds that he can later activate. Each day, he can implant a number of these tricks equal to 1/2 his mesmerist level (minimum 1) plus his Charisma bonus (if any). He can have only one trick implanted at a given time, and implanting a new trick ends the previous one (the mesmerist still loses the use of this ability he spent on the previous trick).

To implant a trick, the mesmerist must take a standard action and either touch a willing creature or implant the trick in himself. A creature can be the subject of only one mesmerist trick at a time. The mesmerist can activate the trick as a free action when a triggering condition is met (as defined in the trick’s description), even if it isn’t his turn. The subject must be within medium range (100 feet + 10 feet per level) for the mesmerist to trigger the trick.

The mesmerist monitors for the trick’s triggering condition through a subtle telepathic connection, so he doesn’t need line of sight to trigger it—but anything that blocks telepathic contact prevents him from triggering tricks. An implanted trick lasts until the next time the mesmerist regains his spells.

Once triggered, a trick is no longer implanted, and can’t be triggered again until the mesmerist implants the trick again. The duration of the effect caused by triggering a trick is either instantaneous or appears in the trick’s entry. The DC for any mesmerist trick or masterful trick that requires a saving throw or skill check is 10 + 1/2 the mesmerist’s level + the mesmerist’s Charisma modifier.

The mesmerist knows one trick at 1st level, and learns another trick at 2nd level and every 2 levels thereafter (to a maximum of 11 tricks at 20th level). Each daily use of mesmerist tricks can be used to implant any trick the mesmerist knows. Unless specifically noted in the mesmerist trick’s description, a mesmerist can’t choose a particular trick more than once.

• Astounding Avoidance:  The subject can avoid damage from magical and unusual attacks. The mesmerist can trigger this trick when the subject attempts a saving throw against an attack or spell that normally deals half damage on a successful save, before the subject rolls the save. If the subject succeeds at her save, she takes no damage. If the mesmerist is 12th level or higher, the subject takes only half damage if she fails her save. The benefits of this trick don’t stack with those of the evasion or stalwart class features.
• Compel Alacrity:  A dash of mental speed lets the subject push past her physical limits to avoid an enemy. The mesmerist can trigger this trick when the subject begins her turn within an enemy’s reach. The subject can move 10 feet as a free action without provoking attacks of opportunity. The distance the subject can move increases by 5 feet for every 5 levels the mesmerist possesses, to a maximum of 30 feet at 20th level. The subject can’t move farther than her speed in this way. The movement from this trick doesn’t count against the subject’s movement speed for that round
• Mesmeric Mirror:  An illusory image appears near the subject to throw off attackers. The mesmerist can trigger this trick when the subject is attacked or becomes the target of a spell that requires an attack roll. One duplicate of the subject appears, and the attacker must determine randomly which it hits (as mirror image). For every 5 class levels the mesmerist possesses, one additional image appears, to a maximum of five images at 20th level. Each image lasts for 1 minute per mesmerist level or until destroyed. This is an illusion (figment) effect.
• Slip Bonds:  While implanted with this trick, the subject gains a +2 circumstance bonus on Escape Artist checks. If the subject becomes grappled, pinned, shackled, or otherwise personally restrained, the mesmerist can trigger the trick and cause the subject to become incorporeal just long enough to slip her bonds (unless they can otherwise restrain an incorporeal creature). This effect doesn’t last long enough for the subject to move through walls or other barriers. If the mesmerist is 12th level, the subject remains incorporeal until the beginning of the mesmerist’s next turn.

When an attack that deals damage hits the target of a mesmerist’s hypnotic stare, the mesmerist can cause the target to take an amount of additional damage equal to 1/2 the mesmerist’s class level (minimum 1).

The mesmerist can use this ability as a free action, and can use it even if it isn’t his turn. If the mesmerist uses this ability to increase his own damage, the additional damage increases by 1d6 points for every 3 class levels the mesmerist possesses. This damage is precision damage and is not multiplied on a critical hit. A mesmerist can trigger this ability only once per round, but a single creature can take damage from multiple mesmerists’ painful stares in a round.

a mesmerist’s hypnotic stare imposes a further effect upon its target. The mesmerist chooses one option each time he gains a new bold stare improvement, and the choice can’t be changed later. The mesmerist can’t choose the same bold stare improvement more than once unless otherwise noted. All of the mesmerist’s bold stare improvements affect the target as long as it is affected by the mesmerist’s hypnotic stare.

• Psychic Inception:  The hypnotic stare and its penalty can affect creatures that are mindless or immune to mind-affecting effects (such as an undead or vermin). The mesmerist can also partially affect such a creature with his mind-affecting spells and abilities if it’s under the effect of his hypnotic stare; it gains a +2 bonus on its saving throw (if any), and if affected, it still has a 50% chance each round of ignoring the effect. Ignoring the effect doesn’t end the effect, but does allow the creature to act normally for that round.
• Disorientation:  The hypnotic stare penalty also applies on attack rolls.

the mesmerist can help allies shake off harmful conditions—especially those that affect their minds—by channeling psychic energy through his healing hands. He can use touch treatment a number of times per day equal to 3 + his Charisma modifier. Using the ability is a standard action (or a swift action if the mesmerist uses it on himself ), and the mesmerist must be able to touch his target. He can remove one condition from one target each time he uses this ability. At 3rd level, he can remove any condition on the minor conditions list. At 6th level, he can remove any condition on the minor or moderate conditions list, and at 10th level, he can remove any condition on the minor, moderate, or greater conditions list.

A 14th level, the mesmerist can instead expend one use of touch treatment to replicate the effects of break enchantment.

This targets only one creature the mesmerist is touching and follows all other restrictions of touch treatment.
