Mage Armor when casted on someone with Any Armor

[reichan1331]

I was just told that Mage Armor will replace, doesn't matter who, their Armor that they are wearing.

Example, if I casted it on a Barbarian with Medium or Heavy Armor, the Mage Armor would replace what ever the Armor Bonus is from his current Armor.

I though that, like it says for the description for Mage Armor, that it's an invisible force that surrounds the person. That just adds +4 for their AC and would NOT replace the armor their wearing.

Anyone have any incite into this? Thank you :)

Mage Armor gives an armor bonus. Game-mechanically, named bonuses of the same type do not stack. Instead, you get the higher value.

So you will get the higher of the armor bonus from your armor, or the armor bonus of the spell.

ah ok that makes much more sense then how it was explained before :) Thank you!

And, altho it seems pointless, you can do it if you are facing incorporeals since it is a force effect that generates the AC.

Even with your fullplate (if it is not ghosttouch mind), they bypass the armor bonus. If you have mage armor cast then you at least get 4 points of armor vs their attacks.
