My friends love to prank me in Minecraft, sometimes, they booby trap my house, sometimes, they pour lava where i mine, and sometimes, they steal my apples and potatoes. So, being in the Christmas spirit, they're bound to do something where i'll end up dying and lose all my precious potatoes. This time though, i'll be prepared...

(For the Combination lock part, skip to step: 5)

Anyways, here's a list of materials you need to in order to make this Minecraft build:

  • Quartz Block
  • Sticky Piston
  • Redstone
  • Redstone Repeater
  • Redstone Torch
  • Redstone Block
  • Redstone Lamp
  • Lever
  • Wool block
  • Bedrock (Creative mode only)
  • Iron door

Step 1: Step 1: Building the Base

So for this build, I decided to also add a bit of extra security by having stairs that disappear into the wall, so this base is for that section.

Make the base 10x10 and out of regular quartz blocks. In survival you will need 49 blocks for this part. I'm a moderator on the server so i just switched into creative while making this.

Step 2: Step 2: Building the Disappearing Stairs

For the stairs to disappear the blocks had to be flush with the wall, so I used 5 sticky pistons (on each side) and placed them on opposite sides 1 block away from the edge and then stuck a quartz block to each. Then I made a wall around the entire assembly to hide the pistons and to make it look more aesthetically pleasing.

Step 3: Step 3: the Staircase Wiring

Then, I placed a block of wool on each step (note that this is in the hollow behind the wall) where there was a piston, and put redstone all over it. To connect both sides, I just dug a hole under the building and put a couple of repeaters to keep the signal strong, then attached it to the other side and repeated the same process with the wool. The end picture shows what the stairs look like when the switch is on.

Step 4: Step 4: Random Hallway

For this room, all I did was put quartz blocks on the end of the staircase building and then build a wall around the floor, layer it with bedrock (for blast protection from TNT) and then put another layer of chiseled quartz over the bedrock to hide it. And also, if you're wondering where the roof is, I decided to make it last.

Step 5: Step 5: the Combination Room

This part can be a bit confusing, but i'll try my best to explain it as best as I can. So to build the combination room, start out with a plane about 15 blocks long and 10 blocks wide, and do the same layering as the random hallway we built earlier (Quartz, Bedrock, Quartz). Then, build a wall 1 block high, and 3 blocks from either edge, its shown in the pictures so you can use that as a reference. Then, lengthwise on the small wall, skip 2 blocks and add a block of obsidian, then skip 1 more block and add a final row of obsidian. Once the wall is built, put levers on all of the obsidian blocks, and add a door 1 block Before the far wall (As shown in the pictures).

Step 6: Step 5: the Combination Room (Continued)

Now for the wiring. To enter a combination, switch all of the levers that are part of your combination (e.g. Lever 2, Lever 4, Lever 6), also do this BEFORE adding the redstone, or it wont work properly. Then to make the main switch (a.k.a the Enter button) look at the second image (also note that those are redstone torches, regular torches don't work) and copy it exactly. Next, find the levers that are flipped as a part of your combination by putting redstone torches along the obsidian, the ones that don't light up are your combination. Once you've done this, break all the torches that are lit up, and instead, put a wool block under them. For the torches that are not lit up, put redstone directly under them without a wool block (the fourth picture). Finally, to connect the main circuit (Enter button) and the combination circuit, place redstone on the space between the two parts of obsidian (picture 4). Once that's done, that's it! Now, when a wrong combination is inputted, the door won't open, unless the right one is inputted. Also, i haven't done it here, but I'd suggest to put signs under the combination levers to make it easier to remember your combination.

Step 7: Step 7: the Vault Room and Roof

For this room, the construction is the same as all of the others except that it is smaller, but you can make it whatever size you like. As for the roof, i just added an extra block on the wall and built my roof like that, but you can make yours to be fancier or simpler, depending on what mode you play and how you want it to look. Finally, the lighting is just a layer of redstone blocks, and right under that, a redstone lamp.

Step 8: Step 8: Kick Back and Relax

Now, I can't wait to see how my friends react to this... even when their TNT fails. So that's the end of this instructable! I hope that it was clear and you enjoyed it and if you guys can, please vote for it in the Minecraft contest. Anyways, that's it! Merry Christmas!
