Moxie

Ysoki are scrappy and nimble even when the odds are against them. A ysoki can stand from prone as a swift action. Additionally, when off-kilter (see page 276), a ysoki does not take the normal penalties to attacks or gain the flat-footed condition. When attempting an Acrobatics check to tumble through the space of an opponent at least one size category larger than himself, a ysoki receive a +5 racial bonus to
the check.
