Yeah, no problem. Just pointing out that insanity is not going to follow from this. But plenty of things in the current battle aren't helping Soul Reaver with retaining control of that sword...
As for the current attack, it doesn't (chronologically) complete until Kitharsis does... whatever he plans to do.
If it hits, it's going to hit like a freight train. Soul Reaver's not only powered up, and about to swing with both hands, but if the assault makes contact with Abaddon, it's going to unleash a pulse of energy fueled by the souls' own suffering and desire for revenge against Abaddon.
If the blow misses or is blocked, the energy won't be unleashed (yet).
