Affect Spirts to hit supernatural creatures in DF

[b-dog]

Since I liked GURPS voodoo so much especially with its concept of in-betweeners I always have supernatural monsters need to be hit by weapons that have the enchantment Affect Spirits. I usually have a much higher DR for weapons without Affect Spirits enchantment to protect in-betweeners. This represents the fact that demons, undead, faerie and other supernatural beings are a mixture of both the spiritual and the material.

I have some weaker versions of Affect Spirit like Affect Demons or Affect Undead or Affect Faerie which only allow the weapon to interact with one class of spiral in-betweener entity. A sword with Affect Demons will affect only demons and leave undead unaffected so a ghost or wraith would have their higher DR protection against the sword with Affect Demon enchantment. Likewise a sword with Affect Undead will only affect undead and not give any bonus against demons or faerie.

There can be many type of Affect that can affect only a narrow type of spiritual entity. Affect Angels only affects angels and truly good Divine servitors. Affect Spirits in the mast spell however and affects all supernatural spiritual entities.
