No.8 was not stupid knowing the conditions that Jin set were of a tall order. If she and her Commando Mages fail, they would be a laughing stock among the Dashavatara. Although Jin had kept the circle small by having only Kalki oversee the battle alone as a third party observer, there was nothing stopping the Goddess of War from telling her fellow comrades how pathetic the Commando Mages were.
But this was the reality that they were in right now. Their King was one who have knowledge of their skills and abilities especially when he was the instructor who nurtured and trained these adventurers to their current potential.
Of course, Kraft did play a hand in their training regime but the bulk of it remained under Jin's care. When he said they have ten tries meant that the difficulty spike to win this dungeon instance against the God of Preservation would not be an easy obstacle.
