Natural Health Regeneration
While not in combat, Health regeneration occurs automatically, the rate slowly increasing up to a maximum of 7 pips.

Capping at [-10,10]
The maximum net regeneration or degeneration is capped at 10 pips before application to a character.

Example:
 * If a character is poisoned and burning, they will have a net total of -11 pips, but it will be capped and the player will only suffer from -10 health regeneration. With Healing Breeze of +3 Health regeneration cast upon that character, the net total will now be -8 pips and will not need capping. Note they will not have -7, because capping occurs after summing the regeneration and degeneration on a character. This is very noticable when multiple hexes and conditions are causing so much degeneration on a character, that regeneration from a single source may be useless.
