Capitalizing on their use of flame weaponry, Nod scientists developed a new tiberium-carbon blend that drastically increases the damage done by flame-based weapons. The color of the flame also changes from red to bright blue, indicating that heat has been increased dramatically.
Purchasing the upgrade from the Secret Shrine for 3000 credits greatly increases the damage done by all flame weapons, which includes those of the Black Hand flame trooper, flame tanks, and Purifiers. All ground units and structures will receive massive burning damage; even vehicles as heavy as the MARV will be noticeably vulnerable. It is a natural complimentary upgrade to Black Disciples, since when they are combined Confessor and Militant Rocket Squads will be capable of dealing fire damage. Purifiers will also be affected, making them powerful shock units against the most heavily defended bases, as they have the armor to withstand a lot of fire from defensive buildings and the anti-structure capability to then easily destroy them once the flamethrower comes within range.
The flame instantly decimates infantry squads, and destroys vehicles and structures much more quickly, to the point of being effective against heavily armored vehicles like tanks. A single Purifier equipped with the upgrade can destroy the entire enemy base while walking in Aggressive Stance. The upgrade makes all units affected incredibly dangerous to all ground units, and makes any large scale infantry rush of Confessor Cabals and Rocket Militia upgraded with Black Disciples a very effective tactic.
