Shards of Divinity
Martyr's Plate Armor +1
This crimson-tinted armor empowers its wearer to protect allies even at the expense of his or her own health.
Power (At-Will): Minor Action. You take a –1 penalty to
AC until the end of your next turn, and allies adjacent to
you gain a +1 power bonus to AC until the end of your
Power (Daily): Immediate Interrupt. Use this power when
an adjacent ally is attacked. You take a penalty to your
AC equal to the enhancement bonus of this armor; your
ally adds an equal power bonus to his AC. Both effects
last until the end of your next turn.
