Alchemical Weapon Sources

Grenadier alchemists may use an "alchemical liquid or powder" to infuse a "weapon or piece of ammunition" with an additional effect on the target the next time it is used. This is expensive, and the rules are a bit hazy. Here are some possible reagent that can be used with this ability:

Reagent	Cost	Effect on target hit by bullet (in addition to normal damage)
alchemists fire	20gp	Takes 1d6 fire damage. Next round, takes another 1d6 fire damage.
acid	10gp	Takes 1d6 acid damage.
alkali	30gp	Takes 1d6 acid damage. Double damage against oozes and acid-based creatures.
elemental flux	10gp	Takes 1d6 damage of random energy type (acid, cold, electricity, or fire).
liquid ice	40gp	Takes 1d6 cold damage.
itching powder	60gp	–2 penalty on attack rolls, saving throws, skill checks, and ability checks (Fortitude DC 12 save negates).
pepper smoke	60gp	Covered in red smoke for one round and sickened (Fortitude DC 12 save negates).
shadowcloy	25gp	Target treats lighting as one level darker for one round (natural darkness becomes supernatural darkness, etc.)
sneezing powder	60gp	For each of the next 1d4+1 rounds, target staggered until next action (Fortitude DC 12 save, negates that round).
spellscortch	200gp	For the next minute, must make a Concentration check with a DC equal to 10 + spell level to cast a spell, and all other concentration checks to cast spells take a –5 penalty (Fortitude DC 14 negates).
thunderstone	200gp	Deafened for 1 hour (Fortitude DC 15 negates).
tanglefoot bag	50gp	Entangled: –2 penalty on attack rolls and a –4 penalty to Dexterity and must make a DC 15 Reflex save or be glued to the floor (on success, movement is still halved).
weapon blanch, adamantine	100gp	This powder can coat 10 bullets with a full round of preparation, or can be used for one bullet as a swift action with the Alchemical Weapon ability. It allows the bullet to ignore damage reduction keyed to certain materials.
weapon blanch, cold iron	20gp
weapon blanch, ghost salt	20gp
