DogCow doesn't believe me. I'll let him tell you. =) (/-/ Rampant Speculation /-/)

DogCow:
why’s it turn red?

Slycrel:
It’s your radar overlapping the bubble.  I saw it happen that last time we did the fight.  It does make it look like it’s turning red.

DogCow:
… I’m not convinced. Pretty sure it was red while I was aiming at it.
er, orange.
but you could very well be right.

Slycrel:
Yeah, dunno.  I was watching for it and I thought I saw it once — but it was jsut my radar.
so who knows.

So, to better describe what I saw: The little blob inside the glass orb turns orangish with an outline (similar to how an enemy who killed you is red with an outline).
