Dead Man’s Mail Treasure Map Walkthrough

First things first, you need to get the map itself. Fast travel to the Sand Sea Oasis. From there, make your way northwest towards the Great Sand Sea. Keep an eye on your map; you're looking for the area around the letter 'S' in 'Sea'. You should spot some tents. Inside one of these tents, you'll find a skeleton. Check the loot near the body, and you'll find the Dead Man’s Mail treasure map.

Now that you have the map, it's time to find the treasure. The sketch on the map points to a location near the Shark’s Teeth. The easiest way to get there is by fast traveling.

Teleport to the fast travel point that's closest to Tago's Tower. Once you arrive, head east. You'll eventually reach the spot indicated on the first map sketch.

Here's the slightly tricky part: when you get to the indicated spot, turn around. You'll see the exact location shown on the treasure map sketch. To actually reach the treasure chest, you'll need to go forward and climb up a collapsed pillar.

Once you've successfully climbed the pillar, you'll land near the treasure chest. It requires 3 lockpicks to open. Inside, you'll find the Necropants. These legendary pants will not only help you resist Poison accumulation by 30% but also summon a Spectre to attack nearby enemies. That's all there is to the Dead Man's Mail treasure map quest!
