Grapple is an attack technique which can default to Judo or Sumo or Wrestling. It can also be built into a Grabbing Parry, based on Hand Catch. If you successfully hit with this skill, you've grappled your target.
It is required to set up Pickups.
Grappling is mutual as of Martial Arts: Technical Grappling, though Control Points are not.
