This Mausoleum costs 16,500 coins to purchase from the store. Once you buy the base, you'll need to build up the frame using seven energy. At that point, you'll be able to complete the building's construction by asking seven different friends to work inside the building as staff. You can also fill those positions with five City Cash each, or with any Bonus Staff you happen to have, that will be applied automatically.
Once the Mausoleum has been completed, your Monster population cap will go up by 350 Monsters. Sure, that may not be much, but you're free to purchase and complete more than one, with each raising your population cap accordingly. Keep in mind, as you gain more population, you'll unlock other buildings in the store like the Spooky House and Ominous Estate for homes, and the Haunted Library as another Community Building. This one gives you 600 Monsters added to the population cap, so, as you can see, the Mausoleum is but a stepping stone on the way to bigger and better things.
Keep in mind, though, that you'll need to start small - and slow - in this event to be able to unlock different items and raise your population cap. Start with this Mausoleum (and the Haunted Graveyard) and everything else will fall into place just fine. We'll make sure to let you know if additional Monster-themed Community Buildings are released before this event ends, so keep checking back!
