[3.5] Feat question

[Ishcumbeebeeda]

Hey all. I was curious if there was a feat that increases your uses/day of an ability that's listed as a once per day use. I know there are specific ones like Extra Rage, but is there one that grants an extra use of any once/day ability? (Specifically I'm looking at the Death Touch ability granted by the Death domain)

It doesn't exist as far as I know. But there are plenty of spells deal 1d6 * level or better damage.
