The Wild at Heart

It seems you can unlock this after acquiring a few emberlings. You'll need them to break open certain containers. All 5 recipes require an empty bottle (found in trash piles) and beastie bits (dropped from monsters) combined with a unique ingredient.

Sturdy Tonic- burly burr (courtesy of n0rdicninj0n)

Hyper tonic- mesmerite (rocks with crystals)

Power tonic- fever shard (red glowing rocks)

Smelly- any food (hearts, mushrooms, etc.)

Recall- bloom stone (chests and cracked boulders)

Nothing wrong with the first guide just adding all three elements for those who are new to the game and are wondering what the three elements you need to craft the Tonics. side note you will need the Red Spritelings which handle fire before doing the Mix Master achv. There story related and can't be missed. If you smash everything on your journey which you will have to do in order to make things you will get all the necessary items to make your tonics.

Sturdy Tonic - Empty Bottle/Beastie Bits/Burly Burr

Hope this helps anyone who was wondering what they needed and how to do it ;D
