just think of the percentage as points... If you use 5 percent in a battle then just consider that 5 points (keep in mind I have no idea what amount is used in a battle since I have never used any of these before)

It is more likely that it gives a benefit per hit and that uses a certain amount of points/percent of what you have.... per hit...

or a benefit to resistance per defend from a hit and that uses a certain amount of points/percent of what you have....

This could be Wayyyyy off but kinda seems like what she must be saying.
