about the imp shaman, i don't know as i haven't gotten that far. he just may be tough, like fergus. i noticed that some characters in this game have the ability to heal and use it wisely.
as for the alchemy:
1) make sure the character with the skill is the one selected with gold.
2) notice there are different colors of alchemy plants. the colors do not correspond to potion colors. actually, the alchemy, when right clicking the plants, works like this: you select your size of potion, then the type. that type is a combination of 2 or 3 different colors of alchemy plants. look closely at the plant groupings and notice which ones decrement when you create a potion. hence if you are missing a component color, that particular potion will be grey. they will all be unavailable if the wrong character is selected while attempting the skill.
3) it doesn't matter which color you click on to activate skill as the skill will use the appropriate type in potion mixing.
