Internal Alchemist

An internal alchemist studies medicine, diet, and the living body to purify themself in the hope of gaining immortality by means of alchemical concoctions and controlling vital energy. Internal alchemists develop unusual physical abilities from heightened knowledge of how their body works.

An internal alchemist has the following class features.

Breath Mastery

At 1st level, the internal alchemist can control their breath and the flow of vital energy within their body. Without preparation, they can hold their breath for a number of minutes equal to their Constitution score (after this, they must begin making Constitution checks or risk Suffocation by spending a Full-Round Action preparing themself, they can increase this duration to 1 hour per point of Constitution. The alchemist can survive twice as long as normal without food or water before they start to take penalties. They can put themself into a state of suspended animation as a Move Action, and are then Unconscious and appear completely Dead; they awaken at a preset time or in response to a condition set by them when they enter this state.

This ability replaces Throw Anything.

Bonus Feats

An internal alchemist can select Alertness, Extra Ki, Great Fortitude, Improved Critical (unarmed strike), Improved Initiative, Improved Unarmed Strike, Iron Will, Lighting Reflexes, Stunning Fist, or Weapon Focus (unarmed strike) in place of an alchemical discovery.

Disease Resistance

At 3rd level, an internal alchemist gains a bonus on all saving throws against disease equal to their alchemist class bonus against poison. When they gain the poison immunity alchemist class ability, they become immune to disease as well.

This ability replaces swift alchemy.

Uncanny Dodge

Starting at 6th level, an internal alchemist can react to danger before their senses would normally allow them to do so. They cannot be caught Flat-Footed, nor do they lose their Dexterity bonus to AC if the attacker is Invisible. However, they still lose their Dexterity bonus to AC if they are immobilized, or if an opponent successfully uses the Feint action (see Bluff) against them. If the internal alchemist already has uncanny dodge from a different class, they automatically gain improved uncanny dodge (as a rogue) instead.

This ability replaces swift poisoning.

Discoveries: The following discoveries complement the internal alchemist archetype: cognatogen, elixir of life, grand cognatogen, greater cognatogen, lingering spirit, mummification, and spontaneous healing.
