Roshamuul Quest/Spoiler

Start the quest by traveling to Roshamuul. Only the Thais boat sails there.

Missions of this quest will appear automatically as you interact to the environment. Alternatively, it's possible to ask Sandomo for missions.

Lower Roshamuul: The Giant Traverse
In order to repair the bridge and advance further, the following tasks must be done. Completing a task also awards some Inquisition Gold. Rewards can be managed with Sandomo by the use of the keyword gratitude, and then repairs.

Required Equipment

 * A pick (as of the first day of the test server, Secret Agent Tools do not work)
 * At least 1 bucket of water
 * At least 2 empty buckets

Killing Monsters
It's possible to kill local creatures in order to gain Inquisition Gold.
 * Silencers are worth 1 Inquisition Gold
 * Frazzlemaws are worth 2 Inquisition Gold

Delivering Mortar
Finishing task will award you 100 Inquisition Gold.

Gravel: Use your pick on gravel found on the mountain and the south-eastern shore. You must successfully mine 11(?) gravel rocks in order to get a Bucket Filled With Gravel (note that the bucket will only change once enough gravel has been gathered).

In any case, the large gravel rock disappears and respawns after 5 minutes.
 * If you succeed using your pick, some gravel will appear on the ground. Use it and it will be added to your count.
 * Sometimes, you will fail upon trying to mine the large rock and a Frazzlemaw spawns. If this happens, no gravel is added to your count.

Chalk: enter a hole in the south-eastern area to reach a random cave. Try to keep re-entering the holes until you find a cave with white chalk on the ground. Use the ground chalk to add it to your count, but note that spots that have been used recently won't count. It takes 5(?) minutes for chalk to respawn. After gathering from 11 chalk spots, you will obtain a Bucket Filled With Chalk.

Once you have at least one bucket of gravel and one bucket of chalk, use one on another to create Gravel and Chalk in a Bucket. Use it with a bucket of water to make a Bucket Full of Mortar. Now travel to the bridge on top of the mountain and use your bucket with mortar in a Trough for Mortar. The troughs are next to Mortis.

Gravel + Chalk =  Gravel and Chalk

Gravel and Chalk + Bucket of Water =  Bucket Full of Mortar

Note: you can get water by using an empty bucket on a water tile next to Captain Chelop or the Small Brooks east of Maun.

Lower Roshamuul: The Walls of Roshamull
It's unknown how to progress in this phase.
