End Altar
In the remote corners of the End, on the outer islands, ancient sacrificial altars called End Altars appear very rarely. These unique structures are quite uncommon, requiring active exploration of the dimension to find them. If cheats are enabled in your world, you can use the command /locate structure alt:end_altar to pinpoint their location precisely.
The altars accept glazed chorus fruit as offerings. Dropping exactly 32 such fruits (half a stack) onto the central froglight will grant you a random item. For double the rewards, you can sacrifice a full stack—64 fruits. It's crucial to offer exactly 32 or 64 items: the altar will not recognize other quantities (such as 31, 33, or 63).
Rewards vary widely—from nearly useless chorus flowers to unique resources like arrows of levitation and spire armor trims. Particularly valuable are voided tools, crafted from a rare unbreakable material. Be careful not to damage the structure! While surrounding blocks can be broken, destroying the central froglight permanently disables the altar.
