ok, so I have a player in my game that brought up the question first of all as, "with Magical Vestment, can you use it on something like simple robes or clothes?" I assume yes and the existing robes would just count as an item with an armor bonus of +0.
Then he asked, "now if I cast Mage Armor on myself, would the two bonuses stack together? as one is an enhancement bonus to armor class and the other is an armor bonus?" to this I think no because I am under the impression enhancement just adds to a existing number.
In this current stacking example say we're using Magical Vestment CL 12, I see it as cast on robes (+0) becomes an (enhanced)armor bonus of +3, then Mage Armor is cast and being an armor bonus of +4 simply overrides the +3 because of being the same bonus type.
Anyone know for sure which way it works?
