Innate: After using an ability, Shenshields himself from 50 - 101 (based on level)(+ 14% bonus health) damage for 2.5 seconds. If the triggering ability successfully affected at least one champion, Ki Barrier'scooldown is reduced by 4 - 7.5 (based on level) seconds.
Shen's power manifests as a Spirit Blade that he can control with his abilities.
Active:Shen primes his Spirit Blade for 2 seconds, causing it to project a protective zone around it for 1.75 seconds if he or an allied champion move nearby, causing allies in the zone to dodge attacks.
Active:Shenchannels for 3 seconds, shielding the target allied champion for up to 5 seconds, with the base value increased by 1% for every 1% of target's missing health, up to maximum of 60% bonus at 40% of target's maximum health.
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.
