The soft, floating blocks that make up the Aether's clouds.
Usage
Cloud Blocks make up the clouds of the Aether. By default they have no collision, so the Player falls through them, but passing through one applies Slow Falling and dampens downward momentum, cushioning long falls. While inside a cloud, holding jump grants a levitation burst so the Player can swim upward and float. Wearing Cloud Boots lets the Player stand on top of Cloud Blocks instead of sinking in. Cloud Blocks are destroyed if touched by water. They are used to craft the Totem of Unfalling.
Cloud Blocks generate naturally as the clouds of the Aether. They can be mined by hand without any tool and always drop themselves. Note that they break instantly if water touches them.
