  BindModeHelper, PoseTypeHelper, createStack()
Phase 4 (network): PacketSlaveAction, PacketMasterEquip,
  PacketAssignCellToCollar, PacketNpcCommand, PacketFurnitureForcemount
Phase 5 (events): RestraintTaskTickHandler, PetPlayRestrictionHandler,
  PlayerEnslavementHandler, ChatEventHandler, LaborAttackPunishmentHandler
