Overview

This instance is reached by speaking with High Priest Diru Riwirn in Barindu as the fourth step in progression. If you have already completed it or wish to go for xp and random drops you can tell Gamesh "pool". The walkthrough below is for the progression version. For the Gamesh version you can simply do as you wish.

Mobs in the zone range from 59-62 hitting as high as 900. In addition to the 3 loot dropping rares there are two zonewide drops Larva Skin Cape and Taelosian Runed Girdle.

Start by crawling your way through until you reach Utandi. Hail him and follow his dialog and he will tell you about how creatures attacked him and stole his map. You will need to go to the final room of the zone and find Slime Cube. The Cube hits for around 1k and has no spells or procs. When killed it splits into six smaller, non-agro, slimes which path to various parts of the zone. When they reach their destination they change into Cube Fragments.

Start to backtrack stopping to kill Cube Fragments. They only hit for 600 and have no abilities. Keep killing them until you have collected the four Fragments of Utandi's Map. All that remains is to give them to Utandi to complete the Expedition and get a character flag.
