AntiWarp
From ASSS Wiki
Antiwarp is an ability in Continuum that prevents other users from warping when they are within a certain radius of you (the radius is determined by the Settings). Using Antiwarp usually slows down your recharge rate, depending on the settings.
ASSS can be used along with the ELVL Format to create maps where there are regions where players are not allowed to use antiwarp.
You must be within radar range for antiwarp to work on someone due to the Game Protocol mechanics.
