Respawn Anchor

The respawn anchor is a block that allows players to set their spawn point in the Nether. It can be charged up to a level of 4 using glowstone and this level is depleted by 1 each time a player uses the block to respawn. Use in the Overworld or the End results in an explosion, consuming the block.

From block loot
Respawn anchors can be harvested with any pickaxe at or above diamond tier.

Info
The respawn anchor is used to respawn in the Nether. Note, if the player leaves the Nether having their spawn point set at the respawn anchor, they will spawn there.

When used with a glowstone block, the texture of the block changes, and it starts emitting a light level of two. Up to four glowstone blocks can be used to charge the anchor, the charge of which is indicated with a dial on the side of the block. Each additional piece of glowstone after the first increases the light level by four.

When the block is charged, it can be right-clicked to set the player's spawn. Each time the player dies, they respawn next to the anchor, and its charge decreases by 1. If a player's respawn anchor is destroyed, or its charges have been exhausted, or if the area around it is made unsuitable for respawning, a message is displayed saying "Your [sic] have no home bed or respawn anchor, or it was obstructed", and the player respawns at the world spawn point. Returning through an end portal counts as a respawn and thus depletes a charge.

If a charged anchor is used in the Overworld or the End, the block explodes similarly to when a bed is used in the Nether or the End. The explosion has power 5, and sets fire to surrounding blocks.

When charged, a redstone comparator gives a signal depending on the number of charges: 3 for one charge, 7 for two charges, 11 for three charges, 15 for four charges. An empty anchor gives a signal of 0.

The respawn anchor can also be charged with a dispenser meaning it can now be automatically recharged.
