Resilient Spring: This tightly wound spring often commemorates tasks that involve great physical prowess. A halfling who uses it while casting jump can, as a swift action, choose to sacrifice some or all of the spell’s bonus on Acrobatics checks (up to a maximum of her caster level) for the remaining duration of the spell in order to gain an equal bonus on any one skill or ability check that turn relating to Strength, Dexterity, or Constitution.
