After completing the quest Do No Evil and acquiring the Ava's alerter, players are able to obtain one clue scroll (elite). It can be found in one of four locations, and can only be obtained once.
These locations are not guaranteed and that each player has one preset location. Also, you cannot wear any type of metal armour at the same time, or the alerter will not function correctly.
The alerter will notify you with a "Bwuk", "Bwuk Bwuk", and "Bwuk Bwuk Bwuk" when you are nearby; and finally "Bwuk Bwuk Bwuk Bwuk" when you are on top of the correct spot. Dig on that exact spot to receive the clue. You will need to bring a spade. The one on the tool belt will not work.
On the Iceberg featured in the penguin quests. After getting off the boat, run northwest to the giant ice column seen on the minimap. It's on the northwestern side of the column.
The southwest part of Lunar Isle; west of the astral altar and south of the city. Quick access will require you turning on the Lunar Isle lodestone.
West of the Underground Pass exit into Isafdar in a clearing. For fast access, use a Crystal trinket to teleport to Llyeta and go past traps to get here. If coming from Port Tyras, follow the way you took to get to the camp.
If travelling from the Myreque's Meiyerditch hideout, climb up the stairs in the room to the north, jump to the floorboards, and climb down the ladder just like in the quest. Then, open the door and head directly north across a room. Once outside of it in the clearing, it's a straight run to the crate's location.

These can include Dragon helms, Rune Platebody, 1 yew seed, 1 palm tree seed, 1 Papaya seed, 2 Dwarf Weed Seeds, 2 Lantadyme seeds, 9 antifire (4), 9 prayer potion (4), 9 super restore (4), 8 Battlestaffs, 15 Swamp lizards, Mahogany Planks, 15 Royal Dragonhide, 5 Rune Bars, 2 Uncut Dragonstones, 10 Unicorn Horns, 8 Water Talismans, 12 Onyx Bolt Tips, crystal triskelion key fragment (1, 2, 3), Coins (20,000-100,000) or a Large Prismatic Star.
