So, we're gaming this morning and ran across an issue we were not familiar with. Opposing spellcaster was using Mage Armor to buff AC. Our spellcaster cast a spell with a ranged touch attack. Does the mage armor add to the enemies touch AC? We did some searching and never found anything definitive.
nope. Mage armor is an armor bonus.
When you are the target of a touch attack, your AC doesn't include any armor bonus, shield bonus, or natural armor bonus.
Mage Armor provides an armor bonus to AC. Armor bonuses aren't added to Touch AC. The exception is incorporeal attacks, which are still subject to the bonus from force effects like Mage Armor and Shield.
Awesome news! Thanks for the swift replies.
