In the case of Tang and Adam's Semblances, Yang’s is constantly building a charge whenever damage any damage is taken before unleashing an attack with a maximum output of 200% of accumulated input.

Adam's Semblance only appears to build a charge when he focuses, and only his blade can gather damage to store before discharge.
