He was correct about Widget. Use Pounce, Spectral Strike, and Call Darkness and he can solo the fight. Keep Call Darkness up. Use Spectral Strike every time it comes off cooldown, and Pounce the rest of the fight.
I had 2 tormented souls in the backline -- the first one had forced my lamb out and brought in my rabbit. I won; not sure if the script would work since I don't use them. Seems like a nice strategy though.
