How to Craft and Use End Crystals in Minecraft

• End Crystals can be crafted from 7 glass blocks, 1 Eye of Ender, and 1 ghast tear using a crafting table.
• End Crystals can only be placed on bedrock or obsidian blocks. They explode when hit.
• Place 4 End Crystals around the End Portal on all four sides in The End to summon the Ender Dragon after he's been defeated.

Gathering the Ingredients

Craft seven glass blocks. You can craft glass blocks from blocks of sand using a furnace. Use a shovel to mine sand. Place the sand in a furnace along with wood, charcoal, or coal as fuel. Drag the glass blocks into your inventory when they are done cooking.

Find an Ender Pearl. Ender Pearls are dropped by Endermen when they are defeated. Endermen are tall, black, shadowy figures. They can be found in the overworld in light levels of 7 or less. You can find a large number of them in The End.

Travel to The Nether. Many of the ingredients needed to make End Crystals can only be found in The Nether. You can craft a Nether portal from a minimum of 10 obsidian blocks. Place them in the shape of your portal and then light the inside on fire using flint & steel. Then travel through the portal. Obsidian blocks can be found where still water meets lava. They can only be mined with a diamond pickaxe.

Get a ghast tear. Ghast tears are dropped when ghasts are defeated. Ghasts are large white creatures with tentacles that shoot fireballs. They can only be found in The Nether. You may need to kill a few ghasts before one drops a tear. Be careful not to kill the ghasts over lava. Otherwise, the ghast tear will fall into the lava and be lost. You can shoot ghasts fireballs back at the ghasts by hitting them with your sword.

Obtain a blaze rod. Blazes have a 50% chance of dropping a blaze rod when defeated. They are small, yellow, smokey creatures with rods spinning around them.

Craft blaze powder. To do so, place the blaze rod in the 3x3 crafting grid of a crafting table. Then drag the blaze powder into your inventory.

Craft an Eye of Ender. To do so, open a craftng table and place the Ender Pearl and the blaze powder into the 3x3 grid. Drag the Eye of Ender into your inventory. You should now have all the ingredients needed to craft an End Crystal.

Crafting End Crystals

Open a Crafting Table. You need a crafting table to craft End Crystals.

Place 7 glass blocks in the 3x3 grid. Arrange them around the edges of the 3x3 crafting grid. Leave the center square, and the bottom-center square empty.

Place the Eye of Ender in the crafting grid. Go ahead and place the Eye of Ender in the center square.

Place the ghast tear in the grafting grid. Go ahead and place the ghast tear in the bottom-center square.

Drag the Eye Crystal into your inventory. You have successfully crafted an End Crystal.

Using End Crystals

Place End Crystals on bedrock or obsidian blocks. These are the only blocks End Crystals can be placed on. Bedrock can only be found underground at the bottom layer. It cannot be mined or broken.

Use them as decorative blocks. You can place End Crystals on obsidian blocks and use them as decorations around a house, or palace... or a large temple/mausoleum.

Use them to make traps. End Crystals explode when they are hit. You can place them around the perimeter of a house or village you built. Shoot them with a bow and arrow when enemies get close to them. End Crystals have the same explosive force as a creeper.

Use them to summon the Ender Dragon. If you've already beat Minecraft, you can summon the Ender Dragon again with 4 End Crystals. To summon the Ender Dragon, travel back through The End portal. Place 4 End Crystals around the End Portal on the other side in front of the pillar that's in the center of The End Portal. This will start summoning new End Crystals atop the obsidian pillars and then it will summon the Ender Dragon. Have fun beating him again.
