Narran RuneScape gold is going to have an agility class which is just like the Brimhaven one except more difficult, the tickets you get from it can be traded for a mogre lawsuit which raises your chance at agility, an ultra variant which does increases chance in agility better along with a ultimate version which does the best in upping your luck in agility and Yun'lar is going to have a mini-game in which you kill eachother for tickets but the individual who gets murdered the least gets experience in defence and tickets for mogre armor.
Once you have completed Deep Sea Troubles you can talk to Gompar for a different one known as Shipwreck. Gompar will tell you a ship has sunk when it crashed in the walls of Mogrin. He will want you to fix the wall. Go up to Captain Murk and tell him to sail closer to the wallsocket. He'll do so. You may then dip.
Fix the wall. Go back up to Captain Murk and let him sail a little further away so that you can dip. He will do that. Proceed to the palace (could be entered through some region) and talk to Gompar.
Inform Gompar you mended the wall. He'll thank you and supply you 16,000 gp. Tell him you think the boat belonged to a priest that was sailing this manner. He'll state that he saw a few human beings swim into a nearby cave in a water cliff but it caved in because of little earthquake. Proceed to the cave and mine the rocks blocking it (requires 43 mining.) Go in the cave and it'll be dry in there because the water can not cheap OSRS gold reach far enough to flood it.
