Restoring Patrol Mode

Normally, if a character is revived after dying, he loses his patrol mode (also called keep mode). You can re-trigger the patrol mode of your squad mate's characters.

Simply revive the dead character with Resuscitation skill, and then use Detection (or Provoke) skill near the character. This will restore the character's patrol mode and allow him to attack nearby monsters, assuming he's on patrol mode when he died.

Note that this works only for characters who are in your squad, and it doesn't work for scout's auto-heal.
