The Crawling Depths is a high-level dungeon that is a much more difficult version of the Spider Den.

This dungeon is a source of Potions of Mana, and is the main source of the Doku no Ken and two pieces of the Flesh Collector Assassin ST Set.

The portal to The Crawling Depths is a guaranteed drop from the Sting Spider, a rare spawn within the Mountains.

This dungeon must be completed to earn ‘Explosive Journey‘, ‘Epic Battles‘, ‘Hero of the Nexus’ and ‘Realm of the Mad Godfame bonuses.

The Realm Eye says:
After Arachna exiled her son, he stole hundreds of her unhatched eggs and carried them further inland.
Burrowing deep into the tough mountain soil, he raised his siblings to be capable fighters and defend their new subterranean lair.
The banished son has gradually amassed an army of spider warriors. He craves the opportunity to exact revenge on his mother.


The Crawling Depths Key The Crawling Depths Key is available in the Nexus for 100 Realm Gold.


See the The Crawling Depths Guide for a complete walk-through on the dungeon and all its enemies.



The layout and aesthetics are mostly identical to the Spider Den, in that the dungeon is a modestly-sized cavern consisting of a series of circular rooms linked by short hallways. There are no branching paths possible. Unlike the Spider Den, there will be a destructible web block wall at the boss room entrance, and a treasure room with multiple orange stalagmites may spawn in the path.

There is a chance to find a treasure room, a large circular room containing many Glowing Eggs that have a small chance to drop loot that the boss would have dropped. Multiple of these can exist in one The Crawling Depths, but they are not guaranteed to appear.

Tips and Strategies

The Crawling Depths is a simple maze with only one real pathway - so you won’t get lost here - but you do want to watch out for all the Crawling Spider Hatchlings that spawn from the egg sacs littered across the floor and the other spiders that cause a variety of status effects. If you’re not in a rush, it’s usually worth it to be cautious and clear each room before progressing to the next room.

Like some other dungeons, the entrance to the boss room always faces south. Before the boss room, there is a web wall that will cause rushers to spend some time breaking down the wall before entering into relative safety. This wall does not regenerate health, so take it down and enter into the Son of Arachna’s Lair!

Boss Strategies
When in the boss room, try to clear all the eggs surrounding the room first. If you don’t, then you’ll have a harder time trying to kill the boss. During the boss fight, the Son of Arachna zips around the web while shooting quickly. Around the web are 4 colored eggs in each ‘corner’ that spawn each type of spider encountered in the dungeon itself. After the eggs are destroyed, the boss slows down considerably and its firing speed lowers.

Another way to do the dungeon with multiple people is after clearing the eggs in the boss room half of the people go in the center of the web, and the other go on the outside (with Son of Arachna in the middle). This makes the boss bounce back and fourth so you can sit back and shoot.
