Third Time's the Charm

(Complete Scoundrel, page 80, DnD 3.5)

[Luck]

Your deity smiles upon you.

Benefit

You can expend one luck reroll as an immediate action to use the granted power of the Luck domain an additional time per day. You can only use this benefit immediately after using the Luck domain's granted power (in effect, this feat gives you a third chance to succeed on the roll). You gain one luck reroll per day.
