// WaitForNpcs [optional; Default: true]
// This value affects what happens if there are no MobIds in the immediate area.
// If true, the behavior will move to the next hunting ground waypoint, or if there
// is only one waypoint, the behavior will stand and wait for MobIdN to respawn.
// If false, and the behavior cannot locate MobIdN in the immediate area, the behavior
// considers itself complete.
// Please see "Things to know", below.
