Thanks, I was actually using the Gaze of Despair, but my problem was keeping it on for the duration of the fight. I used it to get 03/05 torture kills on the first three angels, but then the stingray angels would have these combos that came out of nowhere and zapped me 1-2 times, leaving me precariously on the edge for the final two waves. I take it off after the first three torture kills.
But, four more tries, I beat it. One more saw me short a torture kill, and another I was actually up TWO torture kills but bit it when the final angel had a sliver of health. That was frustrating!
But, I've continued the level, and using a torture kill on Joy always brings a smile to my face.
And, thanks again for the tips. We all know I need them!
