Perfect Form, called Super Schnee before being unlocked, is a passive skill unique to Weiss Schnee in RWBY: Grimm Eclipse. It can be unlocked by reaching level 10 as Weiss. This ability increases how much is added to her ultimate bars when she completes a hitstreak (of 24).
Early Acces
During early access, Perfect Form increased the number of special bars refilled by completing combos, from 1 to 2, but was otherwise the same.
