Crypt is a special zone that is unlocked after clearing Bog, and it features 66 unique monsters. Each monster have a chance to drops a gems, asylum keys, candy coupon,pachinko ball. Making them an excellent source for mid/late-game. However, none of these monsters drop Cards.
This zone may be accessed anytime for a duration of 60 seconds, but is locked afterwards and reopens after a one day cooldown period.
While none of the monsters deal any damage in this zone, after 60 seconds pass the screen will change to Singularity's screen. However, this sequence can be avoided if a different zone is entered before the time limit passes, but forfeits any remaining time left in the process.
The following table shows the base HP for each monster in the zone.
