Summoning Portal
The summoning portal is a device built by the count's henchmen that brings the demons from the shadows to our world. The portals are scattered all around the 3 areas of the castle and look like rings filled with a glossy black matter, standing on two sturdy columns and a pentagram just beneath them, on the floor. They begin spawning Desmodiij as soon as the player steps into the room, making it difficult for the player to concentrate on more than one or two points of interest at a time. There are two posiblilities to deal with the situation: the first is to quickly shoot the portal or run up to it and hit it with the cane sword in order to stop it from spawning monsters, then deal with those already spawned; the second is to kill the Desmodiij as they appear. Each portal has a set number of monsters, and after several kills the monsters will stop appearing (1 or 2 may pop out if you re-vist the portal room after several minutes, though). Alternatively, you can simply run past the portal room and only kill the 1 or 2 monsters that follow you into the next room. You can also try to take an alternate path through the castle that bypasses the portal room entirely, most of the time you should be able to find a different route that gets you past the portal room without needing to go in. Once the portal is destroyed, it cannot spawn any more enemies, no matter how many times the player leaves and returns to the room.
