Ravine

Ravine is an earthbending ability that sends out an attack through the surface hitting and knocking all entities in its path.

It takes place in the direction you're looking. The target also needs to be in the same Y level as the earthbender for it to do damage, if the entity is one level bellow (or above), it won't do anything.

Unlocking this ability requires a tier II scroll.

Level IV
As with all other abilities, there are two choices for Ravine's level IV upgrade.

Fissure: Destroys blocks under it and plows through anything in its path!

This destructive earthbending move allows the player to destroy blocks by creating a miniature ravine. In addition, this upgrade allows the ravine to destroy blocks instead of climbing them. This ability is recommended for earthbenders who want to reshape the earth.

This upgrade requires a tier IV earthbending scroll.

Shaking earth: Chance to knock armor and weapons off hit enemies.

In addition, expands the ravine to a three block wide behemoth that destroys any and all mobs in its path. Shaking earth can disarm enemies that are hit with it. This ability is great against no-bender players and weapon-wielding mobs.

This upgrade requires a tier IV earthbending scroll.

Mechanics
The ravine has the ability to climb blocks as long as the block height difference between blocks is one block. Anything more will stop the ravine.
