Usage
At the time of crafting, the Anchored Ender Flagon becomes anchored to the player who crafted it, exposing that player’s Ender Flagon contents to every player for drinking or filling. Because of this, you should only ever craft an Anchored Ender Flagon over a normal Ender Flagon if you need it to interact with Redstone.
The color of the stopper on top of an Anchored Ender Flagon is determined uniquely by the UUID of the player it is anchored to.
Anchored Ender Flagons can be filled and drank from exactly as other Flagons.
Chunk Loading
A placed Anchored Ender Flagon anchors the chunk it is in, keeping it loaded.
Redstone Compatibility
Because the world knows which Ender Flagon inventory to access for an Anchored Ender Flagon, it can interact with redstone exactly as a normal Flagon does. This allows it to be filled and emptied remotely, which makes for some very powerful possibilities.
Obtaining with Commands
The following command can be used to obtain an Anchored Ender Flagon anchored to an arbitrary player by UUID:
/give @s buffs_potions:anchored_ender_flagon[buffs_potions:flagon_anchor={player:[I;0,0,0,0]}]
This facilitates multi-channel wireless redstone in creative.
