As to be expected with an ant queen you WILL have lots of other ants add to the fight. And they hit very very fast because she casts a crazy powerful haste. My merc died, I had to finish her off solo and with a mob of ants around me after she died I had to evac. I saw the message about her death. But, as sometimes happens, the quick evac lost me the kill credit. So have to kill her again, alas!
Probably worth the prep to clear most of the ants in the queen's room. What I did was root them all away from her using paralytic spray---prior to engaging the queen. Then I evac'd and ported back. But my stoopid merc decided to engage one of the rooted ants during the fight so the Ant Queen moved TO him, instead of summoning him (I don't think mercs get summoned, right?) and that meant we had to fight the Queen and about 8 soldier ants all together.
Dumn stoopid idjut mercs.. well, after all, he is of the ogre persuasion.
