The Vampire Lair is a structure found in dark forests. It's built primarily out of blackstone and deepslate. The Vampire Lair contains many rooms with loot and has a guaranteed chance of having a stone mask in its treasure room.
Vampire Lairs generate exclusively in dark forests. They have a fairly high spawn frequency, roughly the same as a village (around every 500-600 blocks), however the limited biomes that they can spawn into makes them considerably rarer.
Structure
Vampire Lairs are resemblant of a medieval castle despite being buried in the ground. The Lairs are made up of a vast array of rooms filled with traps (mostly inactive) and treasure. The structure itself also is the only place Vampires can naturally spawn. The entrance is a long house in the shape of a tomb. Opening the trapdoor to what would be the corpse reveals the entrance to the Lair.
The Lair is primarily made up of long corridors, a smithy room, a master's room (treasury), an armory, a pantry, a library, a dome room (rare), and an enchantment room.

The Lair also has traps scattered in some of its rooms. The smithy can have a tripwire trap that will pour lava on the victim's head and the enchantment room can have a sound activated trap that will drop a tnt minecart in front of the player. The TNT minecart does not fall far enough to explode and a majority of the time the trap won't drop the minecart at all.
