Ragnarok Ground Zero/Monsters

Monsters

 * When you kill a monster without boss protocol, a monster with boss protocol will appear (they negate certain skills and statues, including knockback, HP display bar, and monster sense). Taken from Ragnarok Gravity.
 * Doppelganger, or Biolabs characters will appear at midnight.
 * There are returns of pre-renewal monster spawn along with post-renewal. The spawn rates are double the amount and capacity.
