When it comes to antonyms for the word "more necromantic," one could consider terms such as "less magical," "more mundane," or "less supernatural." The word "necromantic" typically connotes the use of magic or spells associated with death or the deceased. So, words that could be considered opposite in meaning would be ones that suggest a lack of supernatural elements or death-related magic. Alternatives include words such as "unmagical," "ordinary," or "everyday." However, it is important to note that it is not just the absence of magic that makes something an antonym of necromantic, but also if the term refers to something that is different in nature or purpose.
