I would suggest that they make their roll at the right DC but then there would be factors that would make the DC go up or down. Have rules in place where if they get the roll with the additional DC they can hit the nail on the head. If they miss by 5 - they miss by a few feet or so. And so on. This would make them still make there shot successfully without the additional DC but not as accurately.

In Example:
Fireball
Reflex save half damage.
Now there are no rolls for targeting something - so take another's suggestions about wind conditions and other things and say they are targeting a ship. Ship is in winds of 30mph and is 600ft away.

DC10 to hit ship - as per wind suggestion
DC15 to hit sails
DC20 to hit steering

The caster would roll d20+spell level+caster level to accurately hit something I would assume. So this would be a really easy system to implement and make for some fine misses. The caster would have to declare what he is aiming for and then the chaos would ensue if he misses by 5 or more.

Adjust these numbers accordingly and have fun!

Oh, here on Earth we can see out at sea at about 20mi before the Earth's curve takes over. So adjust for sight based on something like that as well.

If this boss is truly a sadist, how about having her torture victims be here as well. Have your mechanical soldiers be that but the bodies of alive victims are inside. That would make it a challenge to avoid them and not kill the people inside.

For a last stand, you can always houserule it that she is impaled through the stomach and grips the player's hands and pushes herself further up the blade and does one finally swing vs flat-footed.

Another way to antagonizing the players is, if there are victims to be played with, you can have a trap triggering on a shackled prisoner forcing the players to rush and trigger more nasty surprises.

I don't know what the backstory is of this character so these ideas may not work.

The final boss room could have fall away floors so that a shadow dancer can teleport easily throughout while the characters have to find the places that are safe.

A lot of the other people's suggestions sound good, too.

Have fun!
