If there is no ally within the zone it will not activate for 2 seconds or until an ally comes into range.

280 / 560 / 840 (+ 216% AP)
Upon completing the channel, Shen and his Spirit Bladeblink to the target ally's location.
Shen cannot target himself but can alternatively target allies by clicking their portraits on the right side of the screen or by using the F2 - F5 keys (none of this can be done if he is affected by nearsight)
Stealthed allies are not revealed by Stand United.
Shen will continue channeling and eventually blink so long as Stand United's target is alive (even if the shield is broken)
Interrupting Stand United's channel will not remove the shield prematurely.
