Burn

Burn is a status effect that causes the affected unit to have decreased HP regeneration for three rounds. The amount of reduction conferred is equal to the intensity of the effect. 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
Burn, rather than only representing immolation, can represent the effects of any number of attacks that cause additional short-term harm to their targets. For instance, it might represent a stinging pain, an acid burn, or the effects of shock.
