Beacon

The Beacon is a block used to provide both a unique landmark, and selected buffs to all players in the vicinity. It is activated by placing it as the final block on top of a pyramid formation made up of one to four levels of mineral blocks: diamond, emerald, gold or iron, in any combination. The smallest pyramid that can be made to work with the beacon block has 1 level and consists of 9 mineral blocks. By widening a Pyramid by one block across an entire side, you can widen the pyramid, allowing you to place another beacon without having to build an individual pyramid; Saving time and resources.

The beacon will then emit a light blue beam of light into the sky, and its GUI will be available for choosing and activating the desired enhancements or protections. The range of these effects varies with the pyramid size. All players within range will have the chosen effect applied every few seconds, but when players move out of range, the effect will expire within 4–8 seconds.

Usage


When the player crafts blocks of iron, gold, emerald or diamond and places them in a solid pyramid shape beneath the Beacon block, it will emit a light blue beam of light into the sky and can apply temporary buffs (or Powers) to the player once activated, which refresh every few seconds. The more levels a pyramid has, the more powers are available to choose from. Note that the type of block used to build the pyramid has no effect on its functionality, so it would be more efficient to build your pyramid out of iron blocks because of their relatively low rarity. There are currently 4 levels of pyramids. (Not counting the Beacon block): Level 1 Pyramid - requires 9 blocks (3x3 base) Level 2 Pyramid - requires 34 blocks (5x5 base + 3x3) Level 3 Pyramid - requires 83 blocks (7x7 base + 5x5 + 3x3) Level 4 Pyramid - requires 164 blocks (9x9 base + 7x7 + 5x5 + 3x3) It is possible to mix and match the blocks used in the pyramid (both emerald and diamond blocks may be used to form a single pyramid, for example). It is also possible to combine 4 Beacons (arranged 2x2) using a base layer of 10x10 (so 2x2 = the 4 Beacons on top, then a 4x4 layer above a 6x6 layer above an 8x8 layer all on top of the 10x10 base). Combining 4 Beacons in this way requires a total of 216 blocks.

The beam of light is visible from up to 256 blocks away, and is even visible in unloaded chunks. This provides a useful marker for short to mid-range gameplay. The Beacon beam ends at roughly y:470 as of 1.4.7. Therefore, going up to 470 causes the beam to disappear, and going back down will make it appear again.

Requirements/Effects
The Beacon requires a clear view of the sky. Light level will not make any difference, so you can build beacons in places such as the End. You can also use transparent blocks above it as well.

Powers will be applied to the player while within the area-of-effect of the Beacon, with larger pyramids giving larger areas-of-effect. The type(s) of block(s) used does not affect the power, radius or abilities of the Beacon block, as long as they are iron, gold, emerald or diamond blocks.

Activation
The Beacon itself provides no powers by default. To activate it, place an iron ingot, a gold ingot, an emerald or a diamond into the GUI slot. The player can set the power by clicking on the top window: clicking on an effect will activate it. The item will be consumed and the Beacon will begin providing the power to nearby players when "Done" is clicked. To set a Beacon to a different power, another item must be consumed.

Powers
If the pyramid is damaged so that the Beacon is deactivated, it will still remember what powers it was set for and once the pyramid is repaired, it will resume its previous function at no additional resource cost. This applies to pistons as well, making it possible for players to build Beacons that can be turned on and off with a sticky piston removing or replacing a block on the pyramid. The powers will always be activated within the area-of-effect of the pyramid which grows with each level. Outside the area-of-effect, the powers will last 4–8 seconds.

Regardless of what level the pyramid is, only one primary power may be selected. Higher level pyramids merely serve to unlock more powerful buffs and increase the buffing area around the Beacon block. In order to have an area that gives off multiple buffs, multiple pyramids and Beacon blocks must be constructed.

Primary & Secondary Powers
The five primary powers are: Speed: Increased movement (similar to a potion of swiftness). Haste: Increased mining speed. Resistance: Increased armor rating. Jump Boost: Increased jumping distance. Strength: Increased melee damage (similar to a potion of strength).

Level 4 pyramids can also select a secondary power. This can either be Regeneration or a level II variation of the selected primary power. When selecting the level II variant, Regeneration is no longer provided by the Beacon.

Level 1 Pyramid - (Speed or Haste) Level 2 Pyramid - (Speed, Haste, Resistance or Jump Boost) Level 3 Pyramid - (Speed, Haste, Resistance, Jump Boost or Strength) Level 4 Pyramid - (Speed, Haste, Resistance, Jump Boost or Strength & Secondary Power)

Other Dimensions
The Beacon will function partially (no light beam but it will provide powers) within the Nether as long as there are at least fourteen empty blocksdoesn't work in 1.4.2 above it. Pyramid size has no effect on this distance. This is possibly a glitch as breaking through the bedrock ceiling (causing the light beam to appear) and subsequently filling the hole will prevent this from working.

The Beacon doesn't work in the Nether, unless you enter creative mode and destroy all blocks above the Beacon. This is not a glitch, as the Beacon must have access to the sky, which is always blocked by bedrock in the Nether. The beacon works fine in the void above the Nether.

The Beacon functions normally in The End.

Range of Power
The Beacon forms a cube around itself, the size of which depends on the pyramid type.

Since these cubes are centered around the Beacon, the radius indicates the distance from the Beacon to each side(in all 6 directions).

The buff has the same radius below the beacon as it does to the sides, however the buff travels up to the world ceiling (250) along the light beam.

Trivia

 * Placing a beacon in a pyramid shaped of blocks can make a resemblance to the Luxor Las Vegas hotel and casino which has the world's strongest beam and can be seen from 275 miles (442.57 km) away.
 * The beacon light generated from the beacon block is 255 blocks tall. It is relative to the beacon block height, so several beacon block beams can stop at different heights.
 * Some blocks like signs are very visible even when seen through several beams, becoming a lot more distinguishable from the rest of the landscape.
 * The beacon light does not disappear until the chunk is unloaded, providing a great means to judge where places are.
 * Adjacent beacons may share blocks in their pyramids, allowing for fairly efficient designs that provide multiple powers.
 * The most efficient design allowing for all powers to be activated at the highest level, is a rectangular pyramid which is 4&times;5 at the top, and 10&times;11 at the bottom. This requires 244 blocks.  Since 6 separate pyramids would require 984 blocks, this is more than a 75% reduction in materials, and only 50% more than what a single pyramid would cost.
 * A single Full-Powered Beacon requires 164 Blocks, this means it requires 1476 precious items (Diamond, Gold, Iron or Emerald) that are equivalent to 23.06 Stacks of Ores (Smelting extra cost for iron and gold).
 * The player can leave a resource in the beacon block without clicking "Done.".
 * The only blocks that can be placed in the beacon's light without deactivating the beacon are anvils, glass, glass panes, iron bars, fences, fence Gates, enchanting tables, cauldrons, ender portal frames, ender chests, piston, piston arms, dragon eggs, heads, cobblestone walls, Monster spawners, and other beacons. (non-opaque blocks)
 * Like other light sources with a luminosity over 12 the Beacon Block's light is powerful enough to melt ice.
 * Despite them being resource blocks, Lapis Lazuli blocks and Blocks of Redstone will not work as part of the pyramid.
 * Despite the new texture edge as of 12w38a resembling Diamond, the block still only needs Glass, Obsidian, and of course the Nether Star.
 * Beacons do not work underwater. This is because beacons require a sky light level of 15 to function, and water blocks do not allow all light through them similar to ice and leaves.
 * When a block is placed next to the beacon, the star's texture facing that block is unrendered. This happens because the block is not considered transparent, even though the texture is transparent. So, the game thinks the player can't see that texture, thus unrendering it.
 * If the player flies more than one block above the top of the light beam, the beam will disappear until the player moves five blocks below it.
 * The Beacon is one of the hardest blocks to obtain. Requiring 3 Obsidian blocks, 5 Glass, and the Nether Star, obtained by beating the Wither, the second and most powerful boss in Minecraft.
 * Water and Ice appear transparent when viewed through the swirling particle effect that you give off while you have a beacon power.
