How to Set a Spawn Point in the Nether?
Finally, in Minecraft, it will be possible to set a respawn point in the Nether, all thanks to the upcoming "Nether Update" and the introduction of new blocks with mechanics!
To set a respawn point, you'll need blocks like Glowstone, Crying Obsidian, and a Respawn Anchor.

The Respawn Anchor is crafted from six Crying Obsidian and three Glowstone.

When placed, this block will be uncharged and look empty.

To charge the Respawn Anchor, you need to use Glowstone.
You can use up to four Glowstone, and the charge level is displayed as a changing block texture.

If the block has a charge, right-clicking it (on mobile devices, long tap) will set the respawn point in the Nether.

If the Respawn Anchor has no charge, after dying the player will spawn in the Overworld.
Attempting to use the block in the Overworld or the End will cause it to explode! Be careful!
