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, money, Sea Weed, Junk 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 at you.
 * You can cut the Cheese, which would give you five Cheese Slices.
 * Ink Pen: You can use it to try and improve the quality of Counterfeit Pass, which would initiate the Nimble check. If successful, would create the Quality Counterfeit Pass, otherwise the pass would be wasted.
