Hey found a potential typo and if it's not a typo I'm looking for rule clarification
RAW
Each model of squirming entrails functions differently when extruded: mk 1 squirming entrails help you keep your balance, so you don’t take the normal penalties to attacks or gain the flat-footed condition when you are off-kilter, and you gain a +4 circumstance bonus to Athletics checks to balance.
Balance checks are under Acrobatics, I was wondering if this is a type or if I'm missing some other sort of balance check that uses Athletics.
Thanks
