  • In forest mode monsters from each waves will not attack even when they are attacked. While in sky mode, the monsters attack.
  • In sky mode, there's a pack of lance mercenaries coming from the opposite side from where the monsters appear. These lance mercenaries will attack the monsters, including treasure boxes, and treasure boxes killed by the mercenaries won't drop anything.
  • All monsters dont drop loots except champion monsters in forest mode and treasure boxes in sky mode.
