Enchanted, What creatures are considered:
Any creature that must be struck with an enchanted weapon to harm it.
Enchanted creatures are often times known to have extraordinary powers. At the top of each Creature information sheet, it will tell you what class a creature is.
When you must strike a creature with an enchanted weapon to harm it, this does not mean you cannot harm it with an ordinary weapon. It means that an enchanted creature will have 2 points x its level as base damage-points against all forms of non-magical attacks or rank weapons (magical weapons (Rank 1 or higher).
If not struck by an enchanted weapon these base damage-points must be damaged away to zero before actually wounding the creature.
Example:
A dragon is attacked by a knight with a non-magical (Rank-0 Lance). The dragon is level #30 and so has 60 base damage-points. EVERY TURN, the knight must damage through these base damage-points to actually wound it.
