　Your ability requires a series of Concentrate maneuvers to maintain. Taking any other maneuver (such as Attack or Move) causes it to switch off. Thus, you can only move one step per second while using it, and can’t attack, aim, etc. Your ability shuts down if you lose your concentration (e.g., if attacked and you fail your Will roll).
You can’t combine this with All-Out (p. 11), All-Out Concentrate (p. 11), or Requires Ready (below). Normally, only switchable advantages that would otherwise stay on without an active effort can take this limitation. A passive ability without definite activation conditions (e.g., Empathy) can also take it; if so, it requires a Concentrate maneuver to use.

　Requires Ready: As above, except that your ability requires a series of Ready maneuvers. This is less of a limitation because foes cannot cause you to lose the ability to ready as easily as they can make you lose concentration. -10%.
