Onigashima Raid not defeated with player dead

Hi, I select Onigashima raid on expert with 3.000.000 Boss life and make almost 1.500.000 damage, if I lost all servant before turn countdown expire what happend? the damage is counted in the reward damage amount? or it is added only if the player downed the boss or the turn countdown expires?
Sorry for my english and thanks for the patience ^_^
