The Beacon Pyramid is arguably the most costly structure in all of Minecraft. It requires a Nether Star, three Obsidian, five Glass (in for the form of a Beacon) and a minimum of nine Blocks of Iron/Blocks of Gold/Blocks of Emerald/Blocks of Diamond/Blocks of Netherite. This, however, has a very helpful effect: It will give all players status boosts if they come within its range, which depends on the pyramid's size.
Beacons require a square number of the aforementioned blocks, the largest amount being 81. Here is a table to understand this:
|Number of Blocks||Total Blocks||Range of Boost in Blocks||New Boosts Available|
|9 (3x3)||9||20||Speed, Haste|
|25 (5x5)||34||30||Jump Boost, Resistance|
|49 (7x7)||83 (1x64 + 19)||40||Strength|
|81 (9x9)||164 (2x64 + 36)||50||Regeneration II|
