Bloodstorm's Hidden Passive

[Klepto]

lol, even though i'm flattered by you thinking i would know anything, i have only been using blood a week, so i'm still new to him and still learning all his quirks. i knew his attack rate increased, but i figured it was due to his morale bar being more full, and that the deeper the colour on the bar was, the stronger his attack was.

I considered the morale bar possibility, but that's not it because what actually made me really notice the source of the damage difference this morning was I was doing tremendously higher damage than usual in the Labyrinth, and I didn't have full health at the time. I kill enemies there in one hit since Bloodstorm hits first, so his morale bar didn't have a chance to increase.

I had considered stars being a factor before, but that didn't make sense. I had considered a number of things but I didn't put two-and-two together until the controlled environment of the Labyrinth opened my eyes to the only possible cause.
