Quoting other warrior experts:

Blind her and use the warrior special move not ON but NEAR her, staying invisible by shadow potion.

Mage: Curse her (survivor curse) several times and then use freeze, blind, elemental hail.

use Banish on her dead knights or Aura of Command so they turn on her.

And there are still scorpions you can use.

In my last game I cursed her, polymorphed her into a sweet little bunny and then used ligthning. This spell follows the targeted victim, cause polymorphed tend to be very fast. (version 1.33/1.34, clean install, no freeze, polymorph bug anymore that's why I tested it)
