An Envoy being carried upwards by a Redstone Levitator.Function
Redstone Levitators are a form of controlled block levitation that can be used to make elevators or as a Redstone component.
When powered, Redstone Levitators will float upwards until they encounter a ceiling where they will stop levitating and become a block again.
Golden Clouds are especially useful for returning a Redstone Levitator back down to its starting position.
Obtaining
Redstone Levitators are quite expensive, each requiring 3 Levita Beads with 2 Redstone and 4 Heliolith Bricks, however for a simple elevator 1 Redstone Levitator is usually sufficient.
