Aggravate Wound

"He received only a flesh wound, but it seemed every move he made dug his armor into the bloody flesh, and every grit of sand got into his skin. It was painful to say the least..."

The wounds on the target become aggravated, dealing 1d6 points of damage. If the initial saving throw fails, each round for the duration of the spell the target must make another saving throw or take twice as much damage (2d6, then 4d6, then 8d6, etc.) until the spell ends. Two successful Fortitude saves in a row also ends the spell's duration. The target must have taken at least 1 point of damage previously, it has no effect on creatures at full health.
