Please excuse the fact that the play in this first part is terrible and that I was still figuring out the rules (The last time I have played this game was the deathless run over a year ago). Rest assured that every enemy killed in this run will be on the successful attempt. The fact that I even have to look out for that is something I only realized when fighting the two Ancient Machines.
Also, there will be some enemies later on that guard switches and similar things that are required to be activated. These enemies may be technically in some way skippable. Whether or not those will be counted as required combats is yet to be seen.
