Neurochemistry

Source Character Operations Manual pg. 45

Neurochemistry is the study of the chemicals that affect creatures’ brains and nerves (or related cognitive systems).
Booster: You bolster the chemistry of a creature’s brain (or other cognitive system), allowing it to ignore the effects of the confused and staggered conditions for the booster’s duration. While the creature is ignoring these effects, the duration of the condition elapses as normal.
Inhibitor: You deliver a strong chemical admixture that interferes with a creature’s neurons (or equivalent), imparting a –2 penalty to Will saving throws.

Breakthrough

You can use the following ability when you achieve the breakthrough for this field of study.
Boost Neurotransmitters (Ex): As a standard action, you can create and deliver a compound that causes a surge of cognitive activity. When injected into a creature, the formula grants the target a +4 enhancement bonus to saving throws against mind‑affecting effects for 1 minute. If the target is already subject to a mind-affecting effect, the target can immediately attempt a new saving throw with a +2 enhancement bonus against the effect. This does not grant a new saving throw if the effect did not originally allow one.
