The Beacon is very useful but very expensive block in Minecraft. Its primary ingredient is a Nether Star, dropped by the Wither boss. Beacons need to be placed on a pyramid of Block of Iron, Block of Gold, Block of Diamond or Block of Emerald to activate. When powered, Beacons must be given the base ingredient of one of the usable blocks to activate (Emerald, Diamond, Gold Ingot, Iron Ingot). Then, an effect can be chosen based on the size of the Beacon that will be given to all players in the vicinity. These effects include higher jumping, swiftness, regeneration, strength, and such forth.
