Arcane Insight (Feat)

Magical insight helps you evade attacks.

Prerequisites: Arcane Caster Level 16, Arcane Shield (Feat)

Benefit: As an immediate action, you can sacrifice one or more prepared spells or unused spell slots and gain a dodge bonus to AC equal to +1 per spell or spell slot you sacrifice. This dodge bonus lasts until the start of your next turn.

Note: This feat lets you use your immediate action at any point prior to damage resolution to attempt to retroactively make a successful attack miss. Obviously, you can also use it before an attack roll. The maximum number of spells or spell slots you can sacrifice with this feat is equal to the number of tiers of spell-casting classes you possess (1 to 7).

Special: This bonus may be used with the same immediate action as the bonus from Arcane Shield, and stacks with that bonus, to reach a maximum bonus to AC of +14 with a single immediate action, at the cost of 14 spells or spell slots. Ouch.
