So, in a sense, this is also the story of what features might still remain with Nocturne HD's newly updated manual skill selection. I knew the process would be painful and take many patient hours to succeed, but I got it done and recorded it step by step. But early in 2012 I decided to challenge its inner workings and make (approximately) 'perfect' demons, namely a void-all Arahabaki and healing/support tank Amaterasu. And while that mostly applies to the infamous ritual of re-rolling inherited skills, there's so much more under the hood that true mastery of Nocturne's fusion can be elusive. By 2021's standards, the original Shin Megami Tensei: Nocturne's demon fusion mechanics are dated and frustrating.
