How many blocks does a full Beacon take in Minecraft 1.18+?
Q. How many blocks does a full Beacon take in Minecraft 1.16, Minecraft 1.17, Minecraft 1.18?
A. To get a full working beacon It will require a total of 164 blocks to form the pyramid you place the Beacon on.
To Activate the Beacons Secondary Power it needs the full 164 Blocks, but if you dont have that many you can still activate the primary power with 9x9 less blocks.
So to activate the secondary power you will need... 164 - 81 = 83 Blocks. Seems wrong ill have to test this.
I just counted the blocks it needs on the bottom layer and it is indeed 81 blocks, just for the bottom 9x9 square! That is a lot of iron! What is that other black bar?
