Regen

Regen is a status effect that grants the affected unit increased HP regeneration. Regen never expires as a result of time, and is removed only when the effect is Dispelled, the affected unit is defeated, or the current battle ends. The amount of regeneration conferred by this effect is equal to the intensity of the effect.

What it Represents
Regen can represent a wide variety of things, such as activation of innate regenerative capabilites, initiating automatic repair sequences, or regenerative enchantments.
