Tips, tricks & notes:

• If you wield an Amulet of Catspeak during your first conversation with King Sorvott, you will see what Hrafn is saying.
• If you pay the 5000 GP tax for Vanligga Gastfrihet, she will give you access to her black market shop of yak products including yak hair, yak meat, yak-hide, and cured yak-hide. You can also pay her any time after the quest.
• As well as access to a new runite rock on Neitiznot, this quest gives you access to an extensive adamantite and mithril mine located north of the west gate on Jatizso.
• Your reward, the winged Helm of Neitiznot, has better stats than a berserker helm, including a prayer bonus. In order to wield the helm, you must have 55 defence. If you lose it, the Burgher will replace it for 50,000 GP.
• Once you have completed the quest, if you buy some rope from Ned in Draynor Village, he will give you 2 ropes for the price of one because you've discovered that he doesn't make the rope out of wool, but instead buys it from a Fremennik who makes it out of yak hair.
• If you forgot bronze nails or other items, the general store in Neitiznot sells bronze nails, needles and thread, knives, and hammers.
• If you can't get Maria to take you to Neitiznot, right-click her to get the option.
• Using Protection from Missiles prayer can help prevent damage while in areas where rocks are thrown off cliffs by trolls.
• Wearing the Fremennik round shield and yak-hide armour during the fight with the Ice Troll King significantly reduces the damage he deals to you with melee and ranged attacks.
