Underground chemists are part of the rotting, fetid underbelly of the alchemical world. While underground chemists can't hold a candle to dedicated alchemists, they're tricky and dangerous with alchemical substances and potions.

Archetype Features

Chemical Weapons Level 2

↪ builds on Evasion (Rogue)

At 2nd level, an underground chemist is able to retrieve an alchemical item as if drawing a weapon. She adds her Intelligence modifier to damage dealt with splash weapons, including any splash damage. She adds 1/2 her level to Craft (alchemy) checks.

This ability replaces evasion.

Precise Splash Weapons Level 4

At 4th level, an underground chemist can deal sneak attack damage with splash weapons. The attack must be her first attack that round, qualify for dealing sneak attack damage (such as against a flat-footed target), and be directed at a creature rather than a square.

This ability replaces the rogue talent gained at 4th level.

Discovery Level 10

At 10th level, an underground chemist can select one of the following alchemist discoveries in place of a rogue talent: concentrate poison, dilution, enhance potion, extend potion, mummification, nauseating flesh, poison conversion, preserve organs, spontaneous healing, or sticky poison. She uses her rogue level as her alchemist level for determining the effects of her discoveries and whether she is able to select one.

This ability alters advanced talents.

Rogue Talents: The following rogue talents complement the underground chemist archetype: black market connections, fast fingers, lasting poison, sniper's eye, and swift poison.

Advanced Talents: The following advanced rogue talents complement the underground chemist archetype: deadly cocktail and thoughtful reexamining.
