Hell Rider

The Hell Rider is an medium-ranged attack used by the Helios Tank.

After it has been shot, it's like a buzz-saw which moves forward on the terrain towards the direction of which it's shot for a short amount of time, leaving fire all over its way exploding upon touching the enemy tank.

Further as it rolls, its blast damage will decrease gradually until it travels a certain distance, which increases with its level, and will explode normally, dealing damage to its surrounding.
