Beacon Block

Beacon Block is a item that gives players special effects while activated in player's Private Island. It is the vanilla and unobtainable version of the Beacon block in Minecraft, not to be confused with Beacon, which is the official version that unlocks at.

Crafting
Beacon Blocks could previously be obtained by using items with the appearance of a Nether Star (such as Catalyst, Day & Night Crystal), but it was patched in later versions, meaning there was a limited supply of Beacon Blocks before the Dwarven Mines were released. Beacons still worked after the patch as they did before, yet don't work in the current update.

Trivia

 * To avoid confusion with their tiered counterparts, vanilla Beacons are called "Beacon Blocks" in Hypixel SkyBlock.
 * Beacon Blocks and Beacons (Numeral) consider as two different types of blocks.
 * After the Dwarven Mines update Beacon Blocks no longer give any buffs and became a decoration item with the lore of "A cool cosmetic imitation of the real thing!"
 * They still shine light so it's still good for decoration but you can't activate the vanilla buffs anymore since right clicking them doesn't do anything. Although if you activated the beacon buff before they disabled them it still works as long as you don't break it.
