Nothing will tell me what they do. I really don't care about the surprise, someone spoil it for me? Please and thank you.

They give temporary effects to your HA.

The less expensive one gives an achievement--they're fake cures and temporarily give your HA some tendrils. Look in the HA forums for previews.

Ah damn, thanks. :C I was hoping maybe they were wearable. Temporary sucks. ;v; Haha. Thanks you, though!

Yeah it does! Dr. Lockheart's always a waste of money, hahaha. P:
