great, they made a do or die party.
Either they overwhelm and destroy their foes, or they die.
They have no crowdcontroll, proper healer or arcanist of any kind.
Prolonged battles are not for them, nor are any battles where they can't just charge and slaughter. Any terrain problems or enemy tactics will screw them over royally.

They don't really have a choice besides power through the tunnels and charge the cells. Then take lead in the follow-up battles to keep dwarf casualties down.

Too bad, a well-rounded party could have done so much.
