Fafnir

The Fafnir was a tier 5 tank that upgraded from and  at level 60.

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 ammunition 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.
 * Avoid debuff-immune tanks, as they are immune to your main method of attack.

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.
 * If you have debuff immunity, this tank is essentially downgraded to an Inferno.

Trivia

 * Fafnir is the name of a dragon in Germanic folklore who is slain by Sigured, a folk hero.
 * This tank was suggested by Knightmare.
