Balance

Balance (Dex; Armor Check Penalty)  This skill, as listed in DDO, is used to increase the speed with which you get up from a prone position after succumbing to one of the many skills or spells that inflict it, which tend to require a reflex save. (This includes trip, a giants pound special, the grease spell, etc.)

Unlike the PnP version, this skill offers no synergy bonuses to Tumble. (Essentially all synergy between skills has been removed in the translation to DDO.)
