A vampire's lair [60x80] (and a possible upper floor [40x40]) (commissioned) (Patreon Version)

Today I have a big vampire dungeon for you. It was a commission from a member of my highest Patreon tier.
These were two very elaborate maps in a short time and now I'm allowing myself a short break before the next project.
At the bottom of this post you can find all maps in zip files as 10/5mb versions and the vtt files.
Credit for the used asset packs goes to Essendi, Synecdoche, Crosshead, Geordi, Krager and the Apprentice of Aule.

A vampire's lair

Descriptions and my ideas on how to use it:

Upper Floor:

A staircase into a crypt. Here is a hidden door that hides the way into the rest of the dungeon. For the hidden door you can first use the map with the closed door and when your players have found the door you can open the way with the other map-version.

The main purpose of this upper floor is to convey a strange feeling. Something is wrong in this place. It starts with the hidden door. There are also violated altars and looted sarcophagi. It is supposed to prepare for the upcoming dungeon. Let's follow the stairs down to room no.1 of the large dungeon (I also uploaded a map where I numbered the rooms with which I will now orientate myself)

1. We go down the stairs and reach the first hall. The sacrificed heart on this stone can only serve to increase the atmosphere or your players can already meet the first inhabitants of the dungeon here, who are busy extracting hearts from people.

2. We move to the right and find another ritual place with a basin to hold blood. Here I would let the first vampire meet our group. Alone and therefore actually inferior to the group, the monster tries to fight in or around the pool. As long as it is in physical contact with the blood, it has enormous regenerative powers. The group either has to get it away from the pool somehow or kill it until the blood in the pool is used up.

3. This number represents several rooms with no specific center. Here your party could meet generic enemies, be given the opportunity to take a short break or something similar. Of course, a surprise can also hide in every sarcophagus.

4. This area is mean. The corridors are winding and narrow. I would recommend several quick enemies, which do particularly high damage if they can encircle a victim. Your group must not split up at this point and should always fight back to back.

5. We enter the bedroom: Here we find some coffins. I would in some way tell your group that there is an enemy in one (or two/three) of these coffins. The question here is: How will your group find out which one of the coffins is occupying without waking the sleeper? And how can they render it harmless?

(In the event that they nail up the coffin, this would also be an opportunity for a fun social exchange with the poor trapped vampire)

6. We come to the pantry:

Poor mortals are stripped of their valuable innards in this room.

In my mind there is an impressive but stupid butcher (with a few servants) who doesn't really care who or what gets through this dungeon. But he looks very very dangerous. His task is to remove organs on behalf of his master. If someone in the group is willing to sacrifice an organ, the group can pass without a fight. (There are a few organs that you can remove do without dying. Alternatively, you could also try to deceive the butcher and sacrifice a foreign organ in a pretended operation)

7. We quickly jump to the northwest: In this ritual chamber a cultist/vampire is busy sacrificing prisoners in order to draw power from the ritual circle. This power is temporarily but not to be underestimated. In the associated chamber there could still be prisoners who could be sacrificed by your group in order to give them this temporary buff for this dungeon.

8. Room 8 contains a portal or a demonic mirror. In front of that fire bowls are lit with red fire.

Here a riddle with a talking mirror could be introduced. Or there is the possibility of exposition and your party could get an opportunity to talk to the BBEG of your campaign via the portal and find out more about him/her. Or the possibility to reveal a weakness of the boss of this dungeon.

9. Here you can find the remains of the many many victims that this dungeon has already claimed. Loot, information, tragic moments are conceivable here.

(If you want to have a monster recommended for this room, you should have a look at this one:

You change the plant into a pile of bones and instead of zombies it creates skeletons and you have an impressive pile of bones, which here has an incredible amount of food to incite endless hordes of skeletal warriors to your party.

10. A great lake filled with blood. Which loot is in the box? And what's lurking in that hole down there?

Here again a monster would be possible, which regenerates strongly in blood. Here it becomes even more difficult for your group because they somehow have to use tricks or force to remove the monster or monsters from the blood lake in order to be able to fight them successfully.

11. We come to the final room:

Here is our villain with a couple of followers. There are also a couple of enchanted statues that shoot magical effects on those who approach the throne without authorization. In the event of a fight, the cultists and the boss would turn out to be a threat, but they would be manageable. When things look bad for the opposing side, the leader has to do something he really wanted to avoid. He tries to get to the high platform and sacrifice some of his blood on the sarcophagus. This will free a much more powerful beast (such as an insane oldest vampire who has been sleeping in this sarcophagus for many thousands of years). Cultists who are already dead will instantly rise again as zombies and the beast will be set free. The real boss fight begins. The only creature that the beast does not attack are its zombies and the person who sacrificed their blood on the sarcophagus.

(In my version, this vampire clan has not one, but two leaders. A couple who sit on the throne together. If they see that the beast has to be freed, they will compete and if necessary fight each other to be the person who drops their blood on the sarcophagus.)
