This is a slow effect, that does not have any effect during the combat but which will, in time, kill the victim. When you wound a target, expend two Magic points to infect him with Bane. Typical variants of Bane is the Mummy's Rot and the knives of the Nazgul.

The target now is very difficult to heal. All attempts to recover Wound Points have a difficulty equal to your Creature Powers skill, and only the Outcome reduces the victim's Wound Points. Each day, you are allowed a Creature Powers roll against the target's Constitution, and the Outcome is Wound points the target takes. This will make him weaker and weaker, killing him in the end.

There is always some specific way to remove the bane you inflict, though you need not know what this is. Remove Curse will find out how it is done. The way to remove a bane can often be a mini-quest in itself, though strong healing powers might work. Healing performed by an attuned character at a Feng-Shui site or with the correct cure also will remove the bane.
