I made this map for Swamp Dungeon.
For some reason the wiki doesn’t indicate portal and NPC positions like other maps. Combined with the fact that it has 4 too many maps, I got tired of alt-tabbing non-stop while questing there for the 5th time, so I made this:
Monsters present in each map are indicated in green.
NPCs and their positions indicated in yellow.
Blue arrows indicate portals between maps (Dungeon 6 to Dungeon 1 is one-way only).
Some other related useful info:
