Note: This is not going to include the recipes for making the various potions - that information can be found in this topic here.
This, rather, is a table that lists what level of Alchemy you have to achieve in order to be able to mix which kind potion.
AFAICT, that info has never posted (comprehensively) to this forum before now.
Note #2: Don't forget to check the Book I FAQ - lots of good links in there. Some other topics related to this one that might be of interest to players include:
- The Cartography Skill Table thread topic (more Cartography discussion - here)
- The discussions of Mercantile skill at this thread topic here and here
- The discussion of Dodge skill that starts here
- A comprehensive explaination of HP & MP formulas here (also: search Unclever Title for effects of minimum HP & MP - e.g. see here) - for discussions of HP & MP regeneration, see also: here (elsol) and here (Arhu)
- elsol's post also goes into details about the DEX/CON and the Bow skill bonuses you get depending on which level of Bows you are (a discussion that can likely be applied to any weapon's skill level!...).
