Dark knight VS HT.

Are you saying that once both arms are dead there is no more seduce at all from HT?

Here's the general layout for HT since I saw some flaws.

Left/Right Pre-heads cast seduce and 1/1. In the main room, left/right heads 1/1, and once the middle head/left arm get down to about 50% HP, they dispel. Both arms cast seduce on their side of the screen, as mentioned before, even without being attacked. It's only once they get to about 50% that they begin to cast mass seduce, but once you get the arms down, there's no more seduce.

I prefer doing legs > tail > wings > arms > heads, simply because I don't want to be >>> and get seduced <<< with the tail still alive.
