A balance-enhancing skill granted alongside Walk on Air by the toe ring's Physical Balance effect.
Extra Steady Balance is one of the two skills imbued by Physical Balance at level five, itself an effect of the Enchanted Toe Ring of the Well-Balanced. Carl gained it in chapter 10 when he equipped the ring on his left pinky toe. Unlike its companion Walk on Air, it was new to him, and the text gave no further detail beyond its name.
A new passive stability skill in Carl's kit.
