When you feel like you’ve explored enough of Serbule and filled out your combat bar with skills you can consider hitting up the Serbule Sewer in Eastern Serbule. It is a portal located at the bottom of a lake, so you can follow the water line and may be able to see it from shore. Many players either do drown or nearly drown trying to get to the portal their first time. Inside you will find Spiders, Rats, Dinosaurs (Deinonychus), Slimes, and a glyph construct called Acid Sigil that will attack you. In the first main corridor turn there’s a gate that leads into the Dinosaur area that has a few loot chests and spawns for backpacks and such.
If you take two lefts in the Sewers, you will go up a pipe and eventually get to a pipe going right that will spit you out into the Serbule Crypt. You will be near Sir Arif who has holed up behind some Fire Sigils he’s created. You can attack these Sigils like any other mob. They will not fight back. If you do not destroy them, they will “blow up” when you walk over them dealing damage. Sir Arif likes any prepared food not containing fish, so you can bring some Sausages or Bacon along if you want to Favor level him to get access to some new skills.
Very Effective: Crush Good: Cold, Fire Neutral: Piercing, Psychic, Acid, Nature Resisted: Poison, Slashing, Trauma Immune: Dark, Electricity (Energy Keys and Cold Elementals) Notes: Very similar typing throughout, making it easy to expect how things will work out.
If you've had your fill of Dungeons, consider heading back to the Serbule section to revisit what you can do with the loot you've accumulated, or head to Serbule Hills to learn about some more skills outside of the basic Serbule ones you need to know about.
