Tank Limit Breaks come from Final Fantasy XIV, where a full party bar lets one role unleash a powerful shared ability. The tank version at level three is purely defensive, greatly reducing damage for the whole party for a short time, so it is saved for raid wide attacks and near wipes. Clips of clutch activations spread through raid streams, kill videos and gaming edits, and the activation sound alone became shorthand online. Even without gameplay footage, listeners recognise it as the moment a group should have died but did not.
