[Blitz]

Wights are one of my favorite units anyway, especially with Jotenhiem. That, or just go with Ice Devils (Blood 5? BBBWWW) and you get your own SC. Two or Three of those with winged boots. Quickness and go. I basicly shoot for them anyways, might as well use them against the VQ.

As for your own SC?

Put the Wight Blades away and get some Herald Lances Give someone a Totem Shield. Eye Shields will blind her. The Harvest Blade (artifact, BBBN hits automaticaly) will take off her legs, while Picus's Axe of Rulership (artifact, DDE) will do the same for her arms.

Something I haven't tried but probably isn't a bad idea...

Angelic host summons 5 angels, all with flambeaus. They fly too. Not sure if FR negates flambeau damage or just the holy pyre, but this might work.

Lastly, if you are in the real lategame any naked VQ won't stand a chance against a few iron dragons.

Of course she'll be back next turn, but I never said there weren't counters.
