Both the Core Rules and Adventure Compendium have received an update with the new Alchemical Items, Potions and their Recpies. Alchemists should now have an easier chance at finding what they need for brewing, crafting and even learning the recipes.
Added some extra rules such as keeping and cleaning bottles and vials of those Potions/Alchemical Items who aren't broken during the process, so they can be used for new items, but also an additional optional rule for their fragility. Foundry World Updated Accordingly

Items Replaced:
- Caustic Vial
- Fire Bomb
- Flash Sphere

Item Modified:
- Bubbling Concoction
- Potion of Might

Highlighted New Items:
- Cleansing Salve: can dissolve the strange substances that often entrap NPCs in certain rooms like Spawn pools
Elemental Concoction: Replaces the fire bomb and can now deal damage based on what type of reagents are used when making it. It's a thrown item with an Area of Effect
- Elemental Vial: Splashing Item which also deals elemental damage based on which reagents are used.
- Purifying Powder: Similar to the one found in the Undertunnels Adventure, this one can also be splashed against certain infesting creatures to cause direct damage
