How to Make an End Portal in Minecraft

Gathering Resources
To make an End Portal in Minecraft, you will need to gather a few specific resources. These resources include 12 end portal frames and 12 Eyes of Ender. You can obtain the end portal frames by finding them inside of a stronghold, which can be located using Eyes of Ender. The Eyes of Ender can be crafted by combining Blaze Powder and Ender Pearls, both of which can be found in the Nether. It is recommended that you bring multiple sets of Eyes of Ender and extra resources in case any are lost during the process. Once you have gathered all necessary resources, you can begin building the frame for the End Portal.
Building the Frame
To build the frame for the End Portal, you will need to place the 12 end portal frames in a specific configuration. The frame should be three blocks wide and five blocks tall, with each corner block being placed diagonally from one another. The remaining blocks should be placed in the spaces between the corner blocks. Once the frame is built, you will need to insert the Eyes of Ender into the frame. To do this, stand in front of each block and right-click with the Eye of Ender until it is inserted into the frame. Once all 12 Eyes of Ender have been placed, the End Portal will be ready to be activated.
Activating the Portal
To activate the End Portal, you will need to use the Eyes of Ender. Once all 12 Eyes of Ender have been placed in the end portal frames, the portal will emit a beam of light. Stand in the center of the portal and throw one more Eye of Ender into it. This will activate the portal and create a swirling vortex in the center. Make sure that you are fully prepared before entering the End Dimension, as it is a dangerous and challenging environment.
Entering the End Dimension
After activating the End Portal, you can enter the End Dimension by jumping into the swirling vortex in the center of the portal. Once you enter the End Dimension, you will be on a small platform floating in the void. The platform will have an Ender Dragon perched on top of it. Your objective is to defeat the Ender Dragon and destroy the Ender Crystals, which will allow you to access the End Gateway and return to the Overworld. The End Dimension is a challenging and dangerous environment, so be sure to come fully prepared with weapons, armor, food, and other necessary resources.
Tips and Tricks for End Portal Navigation
Navigating through the End Dimension can be tricky, so here are some tips to help you along the way:
Bring plenty of resources: Be sure to bring enough weapons, armor, food, and other resources to last you through your entire journey in the End Dimension.
Build bridges: The End Dimension is made up of small islands floating in the void, so building bridges can help you navigate between them.
Look out for Endermen: Endermen are hostile mobs that can be found in the End Dimension. Avoid looking at them directly, as they will become hostile and attack you.
Destroy Ender Crystals: The Ender Crystals are large, crystal-like structures found on the obsidian towers in the End Dimension. Destroying them will prevent the Ender Dragon from healing itself.
Use beds to deal damage to the Ender Dragon: If you bring a bed with you into the End Dimension, you can use it to deal a large amount of damage to the Ender Dragon. Be careful, though, as this can also be dangerous to the player.
By following these tips and tricks, you should be well-equipped to navigate the End Dimension and defeat the Ender Dragon.
