12-17-07, 10:21 PM In tonight’s game the wizard PC cast mage armor on himself and then tried to cast ghost touch armor on the mage armor. I didn’t allow it, I told him you can’t cast a spell on another spell. His argument was that mage armor creates a sort of force field around his body and that it what he cast it on. The discussion went on for a while until I simply put my foot down in order to continue the game.
So who was right in the argument? I still think I am correct, but I am interested to hear some other points of view.

First off, you were correct that Ghost Touch Armor cannot be cast on Mage Armor. The legal target of the spell must be armor, and Mage Armor is not armor it is a spell.

Secondly and IMO more importantly, did nobody realize that Mage Armor is a force effect that applies against incorporeal opponents? It would be completely pointless to cast Ghost Touch Armor on Mage Armor because Mage Armor already does everything that Ghost Touch Armor does. Mage Armor adds it's full value against incorporeal attacks the same a Ghost Touch armor does because it's a force effect. Unless for some strange reason the wizard was trying to grapple a ghost, he would gain no benefit whatsoever from attempting to cast Ghost Touch Armor in that situation.

Really, if you two are going to argue about the rules it helps to know that you're both irrelevant.

LOL :rofl:
I agree.

Yes we did later discover our error. I'm posting this thread because I was more interested in discussion of the precedent it sets, for example, if you create a wall of force, which could be said to be a physical object, can you then cast spells on it? I would agree that if you created something via conjuration you would be able to cast spells on it, but I don't believe it would work on a force effect.

There are no rules against it. As long as the target is legally able to be the target of the spell, then you can go trigger-happy. As for Ghost-Touching a Mage Armor, doesn't Ghost-Touch Armor have a target of "Touched Suit of Armor"? If so, then Mage Armor Doesn't count as a legal target. It doesn't create an actual suit of armor, but a barrier around the character.

You can cast specific spells at least on a Wall of Force. For example a Disintegrate spell can destroy a WOF as can Mordenkainen's Disjunction (it is in the wall of force description) Other spells could be cast on it if it is a valid target. It would not be a valid target for spells like magic missle for example (Must target creatures). You also couldn't target it with spells like Scorching Ray, which can't target objects.
