How do I need to build an End portal?
user
No problem., but it's unclear if End portals are able to be built. My current understanding is that they 'just spawn somewhere'. To find them you need the eyes of ender, which locate the direction of the portals.

To build the Eyes of Ender, you need to gather both ender pearls and blaze powder. Ender pearls can be found by killing Enderman and blaze powder can be obtained by killing blazes in Nether fortresses. Once you have the ingredients, you can then craft the Eyes of Ender.
