So according to the FAQ, Armor from different named sources stacks. I was thinking of casting December's Touch on a Golem in HtH combat, or even one close to someone else, and then using the Student of Conflict, to cast 3 December's Curse on the Golem, sending the Splash Damage the way of the enemy. The Golem would be able to absorb almost all of the damage with an Armor of 4.
Just to make sure though, did I interpret this rule correctly? Casting a spell with Armor 2 and already having Armor 2 are two separate named sources, or am I missing something?
