To craft the Infinity Gauntlet, you must drop:
1x Netherite ingot
1x Copper ingot
1x Redstone dust
1x Lapis lazuli
1x Amethyst shard
1x Emerald
1x Gold Ingot

To use the the Infinity Gauntlet, have it in your offhand slot and right click. Having different hotbar slots selected will use different stones.

Stone Powers:
Reality: Transforms hostile mobs in a radius around the player into passive ones. Projectiles turn into bats. Crouching while using this will only affect entities that you are looking at
Space: Creates a portal at where you look at. Using it again will create a second portal linked to the first. Walking through a portal will teleport you to the other and destroy both portals shortly
Power: Shoots a beam that explodes anything it touches
Time: Freezes/unfreezes time
Mind: Right clicking while looking at a mob will mind control it. Right clicking while crouching and looking at another mob will cause mind controlled mobs to target that mob
