Notes
Black Slime Portal is one of those entries that proves the game's supernatural ecology matters just as much as the named enemies. It is less a character than a breach point, the sort of thing that keeps a fight alive by turning the room itself into the problem.
Contact Protocol
This is a priority target, not background clutter. Shut the portal down with slime before it has time to keep feeding the room, because the spawn pressure is the real danger here.
