A fern

The fern is a species of plant indigenous to Rook Island.

It commonly grows in grassy areas, around and below palm trees and wild grass.

Uses

The fern cannot be used for any medicinal purposes.

Instead, it is best used as cover when hiding from enemy patrols. The fern will typically break an enemy's line of sight, at a distance of up to 3 meters, at which you are officially in danger of being spotted by the enemy.
