Do a series where you have to complete a map wall of all 25 maps in a large world.
Set-up: Generate a new random world in Creative mode and give yourself the following:
25 blocks of choice
25 item frames
25 blank maps (maybe a few extras in case you die with one in your inventory)
2 ender chests
1 diamond silk-touch pick
1 fishing pole
Build a 5x5 wall at spawn as a shrine for your completed map wall. Put the item frames onto each block of the wall. Put down one of the ender chests near the wall with 24 of the blank maps in it. Put the other blank map, the anvil, the bed, the fishing pole, and the silk touch pick into your inventory. If you want to create a beautiful building around your map wall shrine, now is the time to do this as well.
Once your set-up is done, switch the game to survival mode with a difficulty of either normal or hard. You can now begin recording your series.
Your goal is to explore all 25 maps that make up an entire large world on Xbox One.
No stopping to build a house or farms.
You will find everything you need along the way and can only collect what you can hold in your inventory. You can of course mine and smelt to get ores you need for weapons and armor.
Set down the bed as you enter each new map area and set your spawn there. Don't pick up the bed until you have completed exploring the map area just in case you die. Once the map area is complete, pick up the bed and move on to the next map area.
As you complete each map, put down your ender chest and put the map into it for safe keeping (use the silk touch pick to pick up the ender chest and put it back in your inventory).
Once all 25 maps are filled, return to spawn and assemble the map wall.
I hope you like the idea. I've always wanted to see someone try this challenge.
