Tinkering

Basics
Some of your items may be combined via "tinkering" mechanic, sometimes resulting in new, otherwise unobtainable items.

You can only do so in some safer locations; currently, the following locations have such zones:
 * Cassie's safehouse
 * Condo
 * Milk Farm

Recipes

 * Fairy Dust: Can be used with the following items to create their enhanced versions:
 * Lust Tonic -> Lust Tonic+
 * Stamina Drink -> Stamina Drink+
 * Mana Potion -> Mana Potion+
 * Weird Fish: Can be fed with Worms; this can randomly produce nothing, Sea Weed or empty Bottle.
 * Worms: Can be fed to Weird Fish
 * Dull Knife: You can try to cut the Weird Fish with it, but would stop at the last moment when it looks on you.
 * Dull Knife: you can cut cheese into 5 cheese slices. These slices heal 1/5 the amount of the cheese and sell for slightly more. Plus you can throw them on Cassie's face
 * Ink Pen: You can use it to try and improve the quality of Counterfeit Pass, in order to create the Quality Counterfeit Pass.
