As SRM said Above, Weiss has the Schnee Glyphs; Summons, Time dilation, movement, etc likely only scratch the surface. They've had the same power for generations and still haven't mastered it, likely because in a way the power is not a semblance, but rather their semblance is how they activate a power greater than just 1 semblance.

Yang's power shown in Yellow was likely always her "first stage". Maiden powers as shown in the Raven vs Cinder fight dial that up to 11.
