The armour and tool tier above Netherite

When it comes to armour and tools in Minecraft there is a problem with progression. All of the tiers up to diamond can be obtained from the overworld, netherite can be obtained from the nether but no new tier can be obtained after reaching the end and beating the game.

My idea is for a new ore called forbidden dust that would generate rarely in the end exclusively around a rare new structure called a laboratory in the outer end islands. These structures would be made of similar materials to end cities and end ships, the only difference being a few of the blocks would be cracked variants. Inside these structures there will be a functional block called an altar and there will always be one forbidden dust ore that generates anywhere in a 75 by 75 block radius around the altar. The ore will never be exposed to air. If you brew it together with nether wart you get an item called forbidden elixir, which when applied to the altar, makes it open up. From here you would throw in one netherite armour piece or tool and depending on which one you threw in, it would allow anyone using it to have special abilities once the altar drops the finished item and vanishes. A forbidden armour piece would have two more armour toughness points than netherite and allow you to combine two of the different types of protection onto that amour piece. A forbidden tool would deal one more damage than a netherite tool and be faster at mining. Endermen are hostile to anyone wearing or holding forbidden gear.
