Realm of Chaos: Slaves to Darkness (1988), p118 — 226-230 Burning Body

The mutant's body is wreathed in the flickering tongues of hellish flames, and burns with an unnatural light. Increase Toughness by one, and add three to the mutant's fear point total.

The hell-born fire causes an additional S4 hit every time the mutant strikes an opponent in hand-to-hand combat. Opponents in hand-to-hand combat subtract -2/-20 from their to hit throws as they attempt to avoid the terrible flaming heat. Furthermore, when an opponent does hit the mutant, roll a D6. On a result of 1, 2 or 3 the opponent takes one S2 hit from the flames as he moves in close in order to land his blow.

Finally, the mutant may only carry equipment which is of a magical origin or has been granted as a Chaos gift. All other objects touched by the mutant are consumed by its unearthly heat.
