Lumen Sewers and the Deep Cesspit: two new maps for level 100+

Oct 12, 2026

The Lumen Sewers open to heroes from level 100. The entrance is the grate in the blacksmith's yard in the Village of Lumen, and Selene can also take you there for 20,000 zen. The map starts in the Green Sewer (levels 100 to 115) and goes down to the Crimson Sewer (levels 118 to 124), with mutant rats, vipers, kobolds, giant leeches and ghouls.

At the end of the sewers, a portal leads to the Deep Cesspit, from level 125. Selene also makes this trip for 25,000 zen. The cesspit has rooms joined by tunnels, sludge canals with bridges, flooded halls and dead ends with chests. Its monsters range from level 127 down to the Abyssal Cesspit, where the strongest live, at levels 136 to 148.

Each map has two bosses: the Putrid Mother Maw and Grothar the Rat King in the sewers, and the Crimson Watcher and Vorgul, Eye of the Void, in the cesspit. Bosses drop several items at once. Behind Vorgul, a portal for level 150 heroes leads into Devias.

After level 100, the experience from each monster takes your hero's level into account, up to level 250, as in MU Online. In practice, each map pays best in its own range: the sewers are the best place from level 100 to 163, and low maps such as the Celestial Plateau give almost no experience once you are past level 110. Dario's daily delivery now sends heroes from 100 to 124 to the sewers and from 125 to 148 to the cesspit.

Two new posts help along the way: Bartholomew the Old Sewerman in the sewers, and Sister Brunhild the Exorcist in the cesspit. Both maps are also translated into English. The sewer images only download when you enter them, so starting the game stays light.
