The witch causes a creature within 30 feet to age rapidly, empowering the witch in the process.
The target ages to the next age category (adult to middle-aged, and so on). The witch gains a number of temporary hit points equal to 1d10 + her witch level and a +2 enhancement bonus to either Strength, Dexterity, or Constitution for a number of hours equal to her Intelligence modifier. These effects last for a number of hours equal to the witch’s level.
A creature cannot be aged past venerable age by this hex, and it can attempt a Fortitude save to negate the effect altogether. Once a creature has successfully saved against the withering hex, it cannot be affected by it again.
