Degen

Degen is a status effect that causes the affected unit to have decreased HP regeneration. Degen 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 decreased regeneration conferred by this effect is equal to the effect's intensity. This effect can (and often will) cause HP regeneration to be negative, which results in a loss of HP (degeneration) at the end of each of the affected unit's party's turns.

What it Represents
Degen usually represents the effect of deep wounds that cause unstoppable bleeding or the effects of a gradual toxin or poison. It can also represent long-lasting spells or other supernatural phenomena that drain the vitality of their target.
