I know you need to mix critters and monster parts to make elixirs, and that changing the critter changes the elixir. Does it matter which monster part you use, though? Is there any benefit to using more than one per elixir?
I've experimented a bit, and it doesn't seem to matter, but I've only tried the items I have a lot of. There are also no indications in the item descriptions that it makes any difference. I've googled a bit about elixirs, but I haven't found anything that explicitly says one way or the other.
