Combat Enchantment is a Spell Type and a category of of spells in Master of Magic. Like all other Enchantments, Combat Enchantments are meant to have a permanent effect - lasting as long as the Enchantment remains in play. The effect of a Combat Enchantment however does not just apply to one specific target, but rather affects (for example) all units, all enemy units, all Normal Units et cetera, or possibly even the very rules of combat.
