At first it only had 20 MG resistance... not very difficult with the rune sceptre, eye void and/or spell focus items. The eye void and spell focus can be cheaply passed around to multiple mages for either soul slay, enslave mind, charm, etc., . If I see resistance of only 20 on a SC... I'm thinking Capture and Control it's mine... usually via charm.
.
Later its MG resistance was increased with the suit of armor yet this made it really slow. This armor is more ideal for mounted commanders. If I owned the Queen I would not have her traveling solo, she would be with a team of mage supporters and scout decoys.

With her being so slow on the battlefield the idea of stealing control would still be viable in my book. The fire elementals was a good way to take her out. I hope you brought some low level air mages to pickup some of those items.
