RULES: Alchemy Overhaul.

Here is the new Alchemy system I'll be implementing in Arventine. It's based on gathering ingredients to make potions and other fun items. I will be giving out ingredients in treasure parcels, and you can also try to skill check yourself to sourcing some on your own. Also players can do this straight away, I won't be asking for any crafting feats to be taken.
If any other DM wants to implement this into their game, bear in mind the DCs are tuned to the Arventine party, so they might need need dropping for a lower level game.

GATHER ALCHEMICAL INGREDIENTS

(Daily, must be trained in the skillcheck. Forage can’t be used on the same day as Gather.)
Gathering ingredients can be done anywhere, but has contextual environmental skill DCs:
Forest/cave/countryside/plains etc: DC:15
City/Town/Dungeon etc: DC:20
Desert/wasteland: DC:25
Success: Roll a d6 on the ingredient table below.

1 - Ignus 
2 - Aquae 
3 - Aether 
4 - Maga 
5 - Vitae 
6 - Mort 

These can be combined into potions, oils and powders. Preparing a potion takes an hour and the user make a Arcana or Religion check of DC:20 to successfully make the potion. If a player makes potion that fails by 5 or less on the check, he will recover/make instead one ingredient rolled off the table, but the original ingredients will be destroyed.
