Monster Lab is Dr. Viktor's lab used to make Monster Cells!

You can use Monster Cells to:
  • Craft new Monsters
  • Extract Cells from duplicate Monsters
  • Rank up identical Monsters
The Monster Lab is unlocked at level 20 but will need to be repaired first before it can be used.
It can be upgraded to level 5. Each upgrade gives you the opportunity to Rank Up your Monsters to the same level as your Monster Labs Building Level.
