Studies for a Wizard, in how to increase the defensive properties of her spells.

Another interesting mastery; this one boosts the wizard's total armor bonus, but only while one (or more) of the other protective spells are active.

Arcane Armor was first shown at BlizzCon 2008 when the Wizard was unveiled. It's still assumed to be available as of 8 July 2009.
