I'm wondering that because I'd like to make a snake druid specialized in poisons. There is a lot of summoned snake inflicting poisons and the druid himself can use some poison spells and shape shift into poisonouis snakes.
Is it worth it investing into craft: alchemy?
Obviously it would add a bit of variety to the usable poisons but how would you compare them?
I think I found out. It seems like crafting poison always makes better poisons than a poison spell.
