Minecraft (EP)

For whatever reason I could not find a world where a cartographer gave me a map to a structure nearby- nonetheless, I got the achievement after about an hour of walking.

I looked up seeds for villages in v. 1.2.0. and found 2129169517. There are three villages just next to the spawn, the first of which has 6 diamonds. The desert village has a cartographer. What I did was I ran around the world and found a bunch of sugar cane to turn into paper. I traded the paper with him once, then waited for him to level up once. I repeated this process twice more to get him to tier four. This is when he sells the woodland treasure map. For me I needed 16 emeralds and a compass. I had a diamond pickaxe from the first village, so the mining materials was quick. There being 3 villages, I was able to trade various items with a lot of villagers to get 16 emeralds, such as coal, wheat, leather, and raw porkchop. Then I bought the map.

I needed to go southwest to get there. However, It was only one map west, so I basically only had to go south. Like I said, this took me an hour of running/boating. When I finally got to the mansion, it crashed. I had to re-walk another 15 minutes before getting there again. This time, I ran around the mansion with my map in hand for about a full minute before the achievement finally unlocked.

If anyone finds a seed where you can do this achievement in less time, comment the seed number and the time it took you and I will update the guide!

UPDATE: After the latest update, this solution will no longer work due to the changes in how villagers trade. Thanks, Mojang! If anyone has any ideas, please leave them in the comments and I will update the solution accordingly.

Aco2148117's solution is great, but I just wanted to share another good seed I found for those who don't want to walk the 20k+ blocks required for his forest mansion :)

The seed number I found is 667503609. Very close to the starting point, there is a village with 3 cartographers (!) and 2 librarians (which I believe have a chance of spawning as cartographers?). The village is located at 191, 64, 304 (there's a temple nearby with some goodies at the bottom as well). Of the three cartographers, I decided to trade with the one whose first trade was for 25 pieces of papers. (The other two were 26 pieces of paper and 30. I'm cheap, so the choice was obvious.)

His full trade path goes:
25 paper for 1 emerald
1 compass for 1 emerald
9 emeralds for 1 empty map
13 emeralds + 1 compass for 1 ocean monument map
(He also offers a forest mansion map for around 26 emeralds, but I was impatient)

I traded him up a few times with paper, then traded him 5 or 6 compasses to level him up enough that I could bypass the 9 emeralds for 1 map and go straight to the ocean map. If you're looking for a good cave for the iron and redstone needed for compasses (not to mention a good amount of coal), I dug a hole literally straight down at 92, X, 154. (Craft a bunch of ladders first so you can climb back out!) Once you're deep enough (I stopped at 92, 12, 154), make your way toward a couple blocks of diamonds located at 102, 11, 167 (watch out for the lava!) and you'll find plenty of redstone and iron along your path.

The ocean monument isn't too far away, but you'll probably want a boat to shave a few minutes off your time. It's located at 2632, 62, 1735. Pack a good stack of food, some ladders, and some cobblestones (the latter two for building a tower on top of the ocean monument to dig straight down into the Elder Guardian's room) and start heading southeast until you get there. Once you're there, dig down into the monument as I mentioned and the achievement should pop after a minute or so of swimming around and coming back up for air. (I was holding the map in my right hand, not in my shield hand. Not sure if it matters.)

Hope this helps! If you have any questions, please feel free to DM me here or on XBL and I'm happy to assist :)

Found an easy way to get this is less than 30 minutes. The key here is the elytra wings. The tutorial world has them and plenty of fireworks. Stock up on diamond armor, emeralds, iron, paper, wheat, redstone, and anything else you think will come in handy for trading. Also bring an ANVIL, LEATHER, and XP POTIONS. You will need this to repair your elytra wings. Also make sure you are on PEACEFUL mode so you don't die easily.

I used a tutorial world ported over from Xbox One. Once you port it over, it creates infinite world generate. Fly just to the west in the new generation area and you will find two villages (I went directly west from the giant red flag pole you cant miss at spawn). The first has a cartographer. He needed paper, compasses and emeralds before he gave me a map. (Note this was done on version 1.2.3.3, so if hes not there the concept remains the same. Use the elytra wings and fly around until you find a village with a cartographer). As long as you bring the right supplies you should be able to get the map in less than 15 mins.

Now for the journey, I had to go north to get to the mansion. Simple fly with the elytra wings and constantly use fire works. It took me two stacks of fireworks to get there in less than 15 mins. I had to make several stops to repair my wings, so make sure you keep checking your inventory to make sure they arent going to break. If they get close, simply use the anvil and combine the wings with leather and spend xp to repair them.

So first of all, this guide is meant for people who are trying to unlock this achievement by hosting an achievement world from any other device than the x1 (PC, phone, tablet, etc.). You are most likely wanting to use this world, or in case anyone has got a better alternative, feel free to post it. Here is the solution for the Win 10 PC, you can use these worlds for Win10 PC and phone.

Unsure how to import worlds? -> Look at the walkthrough for the game version of the device hosting.
Unsure how to actually unlock the achievement? -> look at the solutions mentioned above.

Now once you have your worlds loaded on another device to host an issue a lot of people apparently encounter is how to locate the tower on the ocean monument with the llama's, the map, the evoker, the anvils, etc. (as I have received this question at least a dozen times).

You should see a dot on the host's cartographers map, I believe in bottom left corner. That means that the player joining on x1 has to travel in the direction North East to get to the host (bottom right would mean North West, top right would mean South West etc.)

Now the way to figure out where North East South and West are is that clouds always move East to West, so use those to get your directions straight. Look up in the sky and see where the clouds go to. If you know East and West you also know North and South. Next part is to walk a bit towards the achievement set up. I remember it being quite a walk but not too bad.

A lot of people have reported this not unlocking, which it didnt for me.

First off, the map must be in your main hand, so its equipped like equipment in the hotbar along the bottom, not in your offhand in the inventory screen.

If it does not unlock, with the map in your main hand, save and exit the game, quit to the dashboard, turn off your xbox by holding in the power button on the console until the machine turns off. Wait 30 seconds+ and turn the xbox back on and load your saved game. After a few seconds / minutes, the achievement should unlock.

I was getting it not unlocking and this is what solved it for me.

One note is he said change it to easy - i did not, and i dont think it makes a difference.

For those who are having problems thanks to the village and pillage update, I was able to buy a map from a fletcher (this guy sell arrows). If you see any villager trading some strange map (not blank map or locator map), give a try.

Hope this helps.

Edit: It was an "map of the forest explorer" sold by an fletcher

The achievement is not bugged, I made it today without problems (v1.193101.0 Oct 2022). Find a Cartographer or turn a Villager into one, then develop your skill to Master and see if he have the Forest map available to acquire, if not, restore your save and try again until it appears. After acquiring the map, just go to the location of the mansion, enter it and view the map, achievement unlocked.

Ok, to whoever might be looking for this in 2022, it seems bugged but, from my experience, what unlocks this achievement is when you get to the woodland mansion on your map you need to juggle it in and out of your off hand, do this repeatedly and the achievement should pop.
