I just went AFK at this creeper XP farm for one hour and came back to almost nine stacks of gunpowder along with almost 30 levels that's not proof enough that you need to build this Farm I don't know what is let's get into it for Minecraft Bedrock 1.21 ideally you want to build this Farm over top of water this is so the mobs on the ground don't slow down the right to the farm but you can still build it over top of land it doesn't really matter that much as well you want to make sure you're not near any big mountains because mobs might on the mountains and slow down the rates of your farm but the first thing you want to do is go 100 blocks into the air so for me I'm at y level 63 so I want to go up to around 163 doesn't have to be perfect just about 100 blocks so as you can see I'm at y level 163 and now to get up and down from here if you have an elytra that would work you can make a bubble elevator but the easiest way to do it is just to take some ladders and since I'm over top of water I can hold down fall all the way and ladders will be placed so I can easily get up and down from the farm now coming back up to the top of your farm on the opposite side of the ladder Place one block there with two chests coming off of that block and then go ahead and put four Hoppers leading into those chests and then make a ring of any solid block of your choice whatever you want around these Hoppers and chests that we've just made and now we're going to make a trident killer to automatically kill the creepers and collect the XP so start off by placing a piston on that chest turn and place a piston turn and place a piston turn and place a piston so it looks like that now you want to take an observer and place it like this so the arrow is facing into the p piston and you want to do that again for all four of the spots so there there there and there and now the final thing is take a redstone torch and place it on the side of the piston and every time you do it you should see that a different piston extends out and then once you place all four it should be going in a continuous loop like this now take a lever place it on the piston and turn it off and this is how you turn the farm or at least the Trident Killer part of it on and off now grab your Trident throw it onto one of the Pistons and the Trident Killer's done you can turn the Trident killer off for now Place eight blocks on top of these making a ring and then continue this up nine more blocks for a total of 10 high 9 10 there we go so now we have a chamber where the creepers are going to fall down come back down to where your chest is break this block and place a slab so we can stand here without the creeper seeing us but we can still collect the XP through this Gap now coming back up to the top of the chamber on any one of the four sides you want to build out seven blocks so 1 2 3 4 5 6 7 and do that for all four sides there we go and now once you have seven blocks coming out from all four of the sides you want to connect all the edges and make one massive platform leaving the 2x2 hole in the middle now that we've got this massive platform up at the top here with the 2x2 hole in the middle go to any one of the sides go out one block up one block and then make a one high wall surrounding this platform and once you have that go to any one of the four corners build out two blocks like that and then on the other side out two blocks do that for all four of the corners and then again fill in this layer now I hope that part wasn't confusing but once you finish it it should look like this now one more time you want to go at one block up one block and then again make a one high wall around this platform now on top of this outer layer of blocks that we just placed you want to take one stair and place it on every single block there we go now that we've got all the stairs place going around go ahead and make yourself an infinite water source on the side trust me you're definitely going to want an infinite water source for this next part because what we now have to do is take one bucket of water and place it inside of every single one of these stairs and if you do it correctly you should see that the water flows perfectly towards this middle but it does not flow in it stops right on this block once you finished doing that you can of course break your infinite water source and so once it's all done you should see that the water flows perfectly towards the middle like I mentioned but it doesn't flow over now I feel like this is a great time to mention if your dimensions are wrong if the water's flowing over if it's not making it far enough if the creepers aren't spawning anything like that if you're having issues you can download this exact world it is the first link in the description you can make sure the farm Works before you build it anything like that definitely go ahead and check that out but there we go we're done this part it's now time to move on to the first layer of of the farm to get started with the first layer come to any of the corners and go to this block right here and build up four you can then break the bottom three and now what you want to do is in either one of these directions count out 20 blocks or if you're too lazy to count out 20 it should take you to one block beside where we just placed so we just place it down here so 20 blocks should take you to right here 1920 and as we can see perfect it took us exactly to that spot and we should do the same thing in this direction 18 19 20 and there we go it took us to the the exact same spot and now we can just go ahead and do the same thing this way and then connect the edges now this one might take you to a slightly different spot but at this point it doesn't really matter we've got our platform inside of the area now that we've got this floating Square here go to any one of the sides go over one block and then place a block skip a block skip a block and do this all the way down and you should have a perfect Gap at the end and then you want to make these rows continuing all the way to the other side and there we go now that we've got this you want to do the exact same thing but in this direction once you finish doing that you should have all these one block gaps where the creepers are going to fall down now this next part takes a lot of time and a lot of resources but as you guys saw in the intro and the title this Farm is absolutely insane so make sure you stick around for this one go to any one of the sides build up three blocks break the bottom two and then copy this exact same thing that we did here up here now if you only want one layer you can make a solid platform but I recommend doing more than one layer because obviously every other layer that you have makes the farm more efficient there you go as you can see I've got the exact same thing up here that I did down here and it's also two blocks high as well if you look straight down you can see that the holes are lined up this is very important now you have to decide how many layers for the farm you want I like to do between seven and eight layers although you can keep it here you can do one you can do 10 however many you want all right there we go I have seven layers now that's what I decided to end up doing and again like I mentioned you can look straight down these holes and see the water down below now that you've got the amount of layers that you want it's time to start spawn proofing to make sure that only creepers spawn inside of this Farm now if you're not aware 1.21 changed it so spiders spawn inside of this Farm luckily for you guys I and a couple of my commenters have helped me to find a fix for this farm so now it works even more efficiently in 1.21 now the first step is making sure that the creepers actually walk through these holes and to do that you need to take a trapo place it and open it up so the creepers think this is a full block and they end up walking through and falling down into our killing chamber so Place one trap door inside of every single one of the holes once you've got one trap door placed in every single one of the holes one of the first changes we have to make from the 1.20 to 1.21 version is placing trap doors here instead of the old way of placing buttons so along this row not in front of the hole but along this row you want to place one trap door on every single block now that all the trap doors are placed go to every block where there's not a trapo look up and place a button so skip a block place a button skip a block place a button this is different from 1.20 where these were actually trap doors now it has to be buttons otherwise the creepers pathf finding doesn't work and so they just stti here if these are buttons they can walk around and they do end up falling inside of the hole so this is the second change that we've made inside of 1.21 now one more important thing when doing this do not just skip to here it is very very important that you go to this level first so you're going to have almost this crisscross pattern of buttons going over the entire roof there you go now your button should be looking like this again very important that you don't miss any of these and our first layer is complete now you want to copy these steps for every single layer that you've built there we go I've copied the exact same thing on every single layer as you can see I have no trap doors missed there's a trap door in every single one of the holes every single one of these spots and there's buttons on all of the roofs this Farm now works during night time but if you want it to work during daytime as well AKA giving it twice as good rates make sure you watch the next part of this video so go to any one of the four corners shift and place a block on top of the trapo with a second block and then you can break that one there and then go out 12 blocks so one two three four five six seven 8 nine 10 11 12 and the same thing this way 1 2 3 4 5 6 7 8 9 10 11 12 do that for all four corners and then make one massive roof over top all right I now have this massive roof over top of our structure and you can see that all this is dark now creepers aren't spawning for me right now because I'm on Peaceful but if you're not on Peaceful they will start to spawn and the final thing that you need to do for this Farm is again on this top layer Place some buttons like we did down here and one more thing really quick that I forgot to mention up here on the roof make sure that you place down torches place down a ton of torches as many as you can make sure this whole area is lit up otherwise mobs are going to spawn up here and slow down the rights of your farm so once you're done the roof should look something like this the final thing you want to do is make sure you're in Easy normal or hard mode and the entire creeper XP farm is completed now to find your AFK spot it can be a little bit complicated and it's different for every single person as you can see I'm standing right here and we did just see that creeper spawn but it changes for everybody maybe you need to be close maybe you need to be far away but but the place that I AFK at when I'm using this Farm as you saw in the intro is right here the slab is here so the creepers won't blow up I'll collect the XP all the creepers are going to fall down and all I have to do is flick this lever and this trident killer is going to automatically kill them now one more cool thing you can do is grab yourself a looting three sword like I have here and hold this out I don't even have to kill them but since I threw down the trient the effects are going to be applied you can see that I'm collecting the XP and the gunpowder is going inside of this chest well that's all for today if you enjoyed make sure to leave a like And subscribe as you can download this world it's the first link in the description and I'll catch you guys in the next one blazed MC out
