Fafnir

The Fafnir was a tier 5 tank that upgraded from Acid and Boomstick at level 60. It had the flame ability.

Design
The Fafnir looked like an Inferno, but the prop cannon has a smaller clone of it, but is orange. The Fafnir itself also had a faint orange aura.

Technical
The Fafnir released flares, which are cubic ammuniton that grow, but accelerate if the tank moves forward.

Along with flares being special, these flares inflicted burning, which is literally the poison effect, that can spread to colliding entities.

As the Fafnir

 * The flare’s acceleration ability is pretty situational on it’s own, because you likely won’t want to move towards a Chain in battle.
 * Try utilizing the burn effect, though; especially in teams. If you hit an enemy of an opposing team while they’re in a large crowd, you can inflict an absolute swarm of damage, due to the burning effect spreading on contact with something.

Against the Fafnir
Do not forget the Inferno itself(which is all the Fafnir is without burn)has horrendous reload for a Machine Gun upgrade. This means; with the correct build and experience in dodging, you can evade the Fafnir’s flares, and kill it.
