Fiery Phoenix is a battle Avionic that can be equipped in the third Avionic Grid slot. While toggled active, the Railjack is surrounded in a fiery barrier, increasing its speed and damage reduction, as well as leaving a fiery trail in its wake similar to Nezha's Fire Walker that inflicts damage to enemies that pass through it. When deactivated, the Railjack will unleash a radial pulse of fire damage that increases based on the duration it was toggled active.
Presently the only Battle Avionic with a continuous Flux Energy cost while active.
Can be used as an excellent speed boost towards objectives (such as the Veil Proxima Anomaly), or to close the gap quickly to make use of Munitions Vortex, Particle Ram and the Ramming Speed Piloting Intrinsic.
Combine with Tether to group enemies before detonating.
