Wrong; these damage calculations include the Servants' own damage-buffing skills.

What you're seeing is Ibaraki's damage after applying her first skill.

What makes her damage about 100k is her class advantage; Berserkers gain a 1.5x damage multiplier against enemies that aren't Shielder or Foreigner class.
