Lost and Found

Walkthrough
Find the ring by locating and touching ???s throughout the area. (This walkthrough was taken from an Allakhazam post.)
 * This is a game of "Hot and Cold" with the NPC you're escorting.
 * Once you talk to the NPC she will follow you fairly closely, making escorting the easiest part of this assault.
 * If one of your teammates talks to her, she will follow them instead.
 * Once you grab your NPC you can exit off either end of the ship.
 * There are are a few krakens in the area but they have a very narrow sound aggro range.
 * When you talk to the NPC, she'll pause for a moment and tell you whether she feels the ring is close or not.
 * Her messages come in varying degrees from "I don't think we'll find anything around here." to "Yes!... it's very very close."
 * When you get the message, "It's very very close!" target around and try to find a ???.
 * If you don't see it immediately, wait about a minute. The ???s appear and disappear VERY quickly, each ??? appearing for a shorter time than the previous.
 * The results from touching a ??? can be any of the following:
 * The Eye of Zahak
 * A hint. Footprints, Strand of Hair, etc. These are not items, just messages you get from the ???
 * Seaweed (Weight effect)
 * A crab. The crab is very weak, but hate is locked on whoever touches the ???
 * Every time you find a hint, your NPC will gain a new ability.
 * 0 Hints- NPC gives you "Hot" and "Cold" messages.
 * 1 Hint- NPC will tell you which member of your party is closest to the ring. Once you get this ability, use triangulation to find the next ???.
 * 2 Hints- NPC will give you exact directions (North, South, Northwest, etc.) where you can find the ring. At this point her "Hot/Cold" directions are actually misleading and you should focus on your #1 and #2 hint abilities.
 * The final ??? will appear for literally 2 seconds then disappear again, so you have to be FAST when clicking. If you are getting mixed signals from the npc it is quite possible that you are on the final ??? and were unable to click it before it despawned.
 * The Rune will appear at the start point.
