When Shiro uses this skill, he will shout "<player name>, banished!"
The banished party member will be teleported to a separate area representing The Mists. There, the player will have to run up a ramp guarded by Spirits of The Mists, and through a teleporter, to return the the fight with Shiro.
In the banished player's place will appear a spirit binder named Bound <profession name>, that will use the same skill set as the Shiro'ken.
Destroying the spirit binder will bring back the banished party member, as well as give the party a morale boost, recharging all Celestial skills in the process.
When Shiro uses this skill on a Paragon or Dervish, they are replaced with a Bound Warrior.
Shiro will never banish heroes, nor a human player partied with only heroes and henchmen.
Shiro will never banish the last player in earshot. This means that he can be solo'd with certain builds, as long as other party member stay very far away.
