Tools of the Trade

At 3rd level, you master the tools you use to create alchemical items and flasks. You gain proficiency with Alchemist's Supplies, Poisoner’s Kit, and Herbalism Kit.

Alchemical Flasks

At 3rd level, you learn to how to craft Alchemical Compounds. When you gain this feature, you learn four Alchemical Flask options of your choice (see “Alchemical Flask Options” below).

Once per turn when you attack a creature as part of the Attack action, you can use one Alchemical Flask of your choice to apply to your weapon. You decide to use the option when the attack hits a creature unless the option doesn’t involve an attack roll. The additional effect of the Alchemical Flask is active for 1 minute on that weapon.

You can also use your action to instead throw an Alchemical Flask up to 30 ft.

You have can create 5 Alchemical Flasks per long rest. If you don't use the Alchemical Flasks before your next long rest the alchemical composition of the Flasks lose potency.

You gain two additional Alchemical Flask options of your choice when you reach 7th and 11th level. Each option also improves when you become a 15th-level rogue.
