When you get to the town of Kyovashad in Diablo 4, you will see quite a few people struggling to get by and in need of help in the wake of Lilith's appearance. Many of them fear to leave the town due to the various monsters and enemies that are running wild out there.
You can help many of these villagers out by completing a few quests around the town. This includes the quest called Menestad Coffers, which has you helping out a local citizen track down a package that has been lost in-transit and needs to be found, leaving it up to you to do just that.
How To Start Menestad Coffers
You can start this quest as soon as you have finished the prologue to the game which brings you to Kyovastad with Lorath, and it is recommended to be at least Level 5 before starting this quest.
You can find the NPC who gives you the quest, Kudomyla the Tithe Collector, just to the left of the town's fast travel point, near the center.
Kudomyla will explain to you that a monk named Bozan left the town to make a delivery to the nearby settlement of Menestad, but has not been heard from since. She fears for the monk and asks you to help find Bozan out in the wilderness to check on him and see if he is okay.
How To Complete Menestad Coffers
If you look at your map, you will notice a large, blue area on the map to the north/northwest of Kyovashad. This area is where you will need to explore in order to track down Bozan, so head out of the town's northwest exit and begin making your way to the blue section of the map.
Be ready to fight, as there will be plenty of enemies to fight along your path to Bozan, mostly consisting of Ice Clan Marauders. They aren't too powerful of enemies, but there are enough that you can easily get overwhelmed if you're not careful and mindful of your health. Just be sure to take them out as you go, and you will be fine.
As you explore the blue section, you will eventually come to a cliff where you can find Bozan slumped against the rock, not looking too good. Luckily, he is still alive and you can speak with him. He will explain that his guards turned on him and left him for dead out here, and because of his condition, he cannot finish his delivery of tithes to Menestad.
He will ask you to finish it for him, and he will head back to Kyovastad. Pick up the Strongbox next to Bozan and start heading to the left to take the tithes to where they need to go.
You can find Menestad real close to where you find Bozan. Again, there will be some Ice Clan Marauders that will make your journey a little tougher, but they aren't anything that you can't handle.
Once you get to Menestad, you can find Telgun the Merchant Lord in the middle of the settlement, who is the person you need to hand off the Strongbox to in order to complete the quest.
