Bane

Enchantment
It is used to make a magical weapon with powers that work only against one type of foe.
Successfully cast before any offensive weapon enchantment, it reduces the energy cost of those spells, but they will work only against the named foe.
For instance, a sword could be made that did +3 damage, but only against orcs – and this would be easier to enchant than a weapon that did +3 against everything. Note that a Bane spell cannot be removed unless the enchantments it controls are also removed.
The same caster who placed the Bane on the sword must cast the enchantments limited by the Bane. The more specific the bane (GM’s decision) the greater the reduction in the other spells’ cost(s). Banes like “All my foes” are not allowed!
