If you've been dealt arcane damage this turn, this gets +1Defense.
<br><strong>Instant –</strong> TAP your hero, destroy this: Prevent the next 1 damage that would be dealt to you this turn.
<br><strong>Temper</strong> <em>(When the combat chain closes, if this defended, put a -1Defense counter on it, then if it has 0Defense, destroy it.)</em>
