necropolis
Cemetery
To the right of this area is a Vampire Hunter. DO NOT disturb him. Leave him alone. He won't attack. He doesn't do anything – you're some vampire hunter! If you don't attack him, other people won't bother you as long as you don't attack any of them. This can REALLY pay off later. Hop up the platforms to the graveyard to trigger a cutscene.
Another Melchiah offspring will attack from near the gravestones on the left. Kill him with the spear along the wall on the left.
THE MAN BELOW WILL KNEEL: After you kill the fledgling near the tombstones and fall back under the platforms, the Vampire Killer Human will now kneel in front of you (as long as you haven't attacked him). This confirms that the humans will not attack Raziel unless you can attack them. You can approach a human and use your Soul Absorption to drain their life force, but DO NOT drain them completely or they will be killed. Unlike social media, once you defeat or injure your human friends, you can't add them back to your friends list to torment them even more.
Jump onto the platforms to the right and enter the area with the block. Pull the block away from the right wall and push it towards the left wall so that it is positioned under the high ledge on the left. To get to the upper area you need to high jump (hold crouch and jump). Once you reach the top, a cutscene will play in the area to the left.
After the cutscene, another Melchiah offspring will attack in the nearby graveyard. If you want, you can throw this specimen at the circular stone with the spikes on it. Go up one of the ramps and you'll come to an area with sunlight and two more Melchiah Vampires. Try exposing them to sunlight to make killing them easier. Open the door with the designs on it. You go down a flight of stairs and then get to the Necropolis WARP GATE (4/14). Activate the warp gate and then open the door on the other side.
Dead Lake/Outside the Crypt
At least two young birds will attack in this new area. They will appear from the left. There are four mounds of dirt in this area and they are fledglings waiting to awaken. You can easily throw them into the lake in the middle of the area. The bad thing about throwing them into the water is that if they land too far down, it's difficult to collect their soul. To the right of this area is a moving block. There's nothing special you can do with it at the moment, but you could move it into the alcove to the left of it (to the left of the pillar) and that would save some time for later.
NOTE: There is a rough wall on the left side of the lake. Keep this in mind for later as it leads to something, but Raziel can't climb the wall yet.
Falling into the lake will take you to the Spectral Realm, where you can explore a number of additional passages in the lake. However, you can't get collectibles there yet because Raziel isn't able to reach them. Carefully hop/glide across the narrow platforms in the lake to get across the lake. On the other hand, there is another Melchiah vampire. Open the door to continue.
There are two young birds in the area with the gravestones. Kill them and then open the wooden door on the other side. If you don't have any other weapon, you can throw the vampires at the spikes on the side of the entrance door.
NOTE: To the right of the exit door in the outside area of the crypt there is a stone block with the emblem of two soul robbers. Keep this block in mind.
