Pharmacologist (Alchemist Archetype)
The pharmacologist has the following class features.
At 1st level, a pharmacologist discovers how to create a cognatogen, a mutagen-like mixture that heightens one mental ability score at the expense of a physical ability score.
It takes 1 hour to brew a dose of cognatogen, and once brewed, it remains potent until used. A pharmacologist can only maintain one dose of cognatogen at a time—if he brews a second dose, any existing cognatogen becomes inert. As with an extract or bomb, a cognatogen that is not in a pharmacologist's possession becomes inert until a pharmacologist picks it up again.
When a pharmacologist brews a cognatogen, he selects one metal ability score—either Intelligence, Wisdom, or Charisma. It's a standard action to drink a cognatogen. Upon being imbibed, the cognatogen causes the pharmacologist to grow more intelligent, wiser, or charismatic, granting him a +2 natural armor bonus and a +4 alchemical bonus to the selected ability score for 10 minutes per pharmacologist level. In addition, while the cognatogen is in effect, the pharmacologist takes a –2 penalty to one of his physical ability scores. If the cognatogen enhances his Intelligence, it applies a penalty to his Strength. If it enhances his Wisdom, it applies a penalty to his Dexterity. If it enhances his Charisma, it applies a penalty to his Constitution.
A non-alchemist who drinks a cognatogen must make a Fortitude save (DC 10 + 1/2 the pharmacologist's level + the pharmacologist's Intelligence modifier) or become nauseated for 1 hour—a non-pharmacologist can never gain the benefit of a cognatogen, but a pharmacologist can gain the effects of another pharmacologist's cognatogen if he drinks it. (Although if the other pharmacologist creates a different cognatogen, the effects of the “stolen” cognatogen immediately cease.) The effects of a cognatogen do not stack. Whenever a pharmacologist drinks a cognatogen, the effects of any previous cognatogen immediately end.
The infuse cognatogen discovery and the persistent cognatogen class ability apply to cognatogens. A pharmacologist must select the mutagen discovery to gain the ability to create a mutagen. This ability replaces mutagen.
The pharmacologist gains Craft Pharmaceuticals as a bonus feat even if he does not meet the perquisites (see Crafting High-Tech Items in the Pathfinder Technology Guide). This ability replaces brew potion.
Pharmacologists lack the alchemist’s skill in creating mundane alchemical substances. Instead, they are masters of creating drugs and pharmaceuticals. A pharmacologist can use his Craft (alchemy) skill to create drugs pharmaceuticals and gains a competence bonus equal to his class level on the Craft (alchemy) check. He does not gain this bonus when crafting alchemical items. A pharmacologist can use Craft (alchemy) to identify potions as if using detect magic
