[@CollectorOfMyst] Well, in the Avatar universe, Chi Blocking is a teachable art to any skilled athlete. It involves using precise jabs and attacks at various parts of the body to block a Chi and disable a bender's bending and any human's ability to move. Tai Lee was a Chi Blocker, and in LoK, many of Amon's followers are also Chi Blockers.

Is that what you were referring to?
