Miser's Fortune( Complete Scoundrel, p. 80)
Items belonging to you and your allies are abnormally resistant to damage.
Whenever an opponent makes a sunder attack or Strength check to damage an object within 30 feet of you, you can expend one luck reroll as an immediate action to force that opponent to reroll.
In addition, as long as you still have one luck reroll remaining for the day, items in your possession receive a +5 luck bonus on saving throws.
You gain one luck reroll per day.
