Dodge on the automaton, she will cast lightning bolt and then move to 80N50E. Assuming that the automaton moves to her last spot and the lightning hurts it, I can summarize a few rounds as follows:
584: Cast see invisibility and move to 80N20E.
585: Cast expeditious retreat and move to 50N20E.
586: Cast scorching ray and move to 0N20E.
587: Cast magic missile and move to 0N80E.
588: Cast divine favor and stay put.
589: Cast divine power and move up next to the automaton.
590: Bite (but do not time compress). Nadia kept out of melee as long as possible.
If the lightning does not affect the automaton, insert the magic missile for Round 584, but keep all the movements roughly the same.
