Dark knight VS HT.

Yeah the heads cast the threatening stuff. I would go for those first. You might be able to crusher both if the side heads move up a little no?

o-o?
No. You can at best Fury two heads at a time, but I don't see why you would want to.

I don't see how killing the right head with both arms doing Seduce can be any harder than doing the same with Tail.
Longer, granted, harder, not really.

Each body part have their own HP, you can leave the arms alone and they won't start using mass Seduce. But they will still use the first-come-first-serve Seduce, which is just as bad imo. Just, perhaps, one is easier to deal with than 2? Maybe.

I believe both the left/right heads do 1/1.
