Drinking Poe

== Routine ==

Generate Random Number between -1 and 1
If 0, set number to 3
If -1, check current health
If health <= 0x10 (1 heart), set number to 3
If health > 0x10, call HP update function to "add" -1 heart to Link's current health manually, and branch out of routine

If still processing, multiply number by 0x10 to represent a positive N heart change (since -1 has been handled).
Write health increase amount to Save Context + 0x1424, which will automatically increment health over time.

== Simple Stats ==

If health > 1 heart:

Even 33.3% chance of 3, 1, or -1 heart restoration

If health <= 1 heart

66% chance of 3 heart restoration, 33% of 1.
