Countess' Fury

[Cheggf]

What is Countess' Fury? The store page doesn't mention it, her wiki page doesn't mention it, none of her skill or tower pages on the wiki mention it, and nothing on google mentions it. The only reference to it I can find are me being able to increase its damage with Ascension and speed with a shard.

Is it the projectile part of her autoattack?

It's the Fire Phoenix that fires with her basic attacks.
