Type: Arcane
Source: Dragon #351
In times of grave danger, you scavenge your spells for immediate protection.
Prerequisite: Arcane Focus.
Benefit: When you expend your arcane focus, you may select one of the following three benefits.
Absorb Damage: As an immediate action as part of expending your arcane focus, you may "lose" a prepared arcane spell or an arcane spell slot in exchange for temporary damage reduction. Until just before your next turn, you gain damage reduction equal to the level of the spell lost in this way. Thus, if you lose a 3rd-level spell, you gain DR 3/- until just before the start of your next turn.
Iron Magic: Each spell granting you an armor or shield bonus grants you an additional +2 armor or shield bonus until your next turn.
Protective Aura: As an immediate action as part of expending your arcane focus, you may dismiss one spell that you cast that currently affects you, such as mage armor or fire shield. In exchange, you receive an enhancement bonus equal to the level of the spell dismissed on the next saving throw you attempt within the next minute. For example, if you dismiss a mage armor spell you cast on yourself, you gain a +1 bonus to your next saving throw; if you dismiss fire shield, you gain a +4 bonus.
Special: A wizard may select Defensive Magic as a wizard bonus feat.
