[Gaming] [Natural Healing]

A rules question in the T&T family of games spurred this thought of mine.
This isn't about T&T, and can readily be used by any D&D-like...
-- Please do consider using it in your TTRPG of choice:

Natural Healing (per permissible use)-

* 'Short Rest': 1d6-2
* 'Long Rest': 1d6-1

* Night's Rest: 1d6
* Bed Rest: Higher of 2d6, +1
* Full Rest: Highest of 3d6, +2

:: If the damage sustained by the character is less than the number on the given die, all damage is healed.
:: If the damage is equal to the modified die roll, the damage is cut in half and remainder dropped.
:: If the damage is greater than the modified roll, subtract the number from the damage.
