Where do roots like 'Mors Anima' in the Archaic style come from?
From a 90-word pool of real and pseudo-Latin vocabulary organized into 9 thematic families of 10 each; 'Mors' (death), 'Anima' (soul), 'Fulmen' (lightning) and 'Ignis' (fire) are genuine classical Latin, while forms like 'Spellum' are invented coinages built with the same endings so they sound consistent with the rest of the pool.
What is the difference between the Invoke style and the Ritual style?
Invoke always opens with a verb out of 20 options (Summon, Weave, Rouse) followed by the target, like a command; Ritual has no verb at all, it builds a noun phrase with the preposition 'of' linking a liturgical noun to a fixed poetic qualifier, reading like grimoire text instead of a casting order.
Do the names follow D&D schools of magic (evocation, necromancy, etc.)?
No: the generator's 4 styles (Invoke, Compound, Ritual, Archaic) are sentence-structure categories, not official schools of magic; a name from the Invoke style can just as easily describe a healing effect as a damage one, so the style is not a substitute for a tabletop ruleset's school classification.
What changes when I turn on hybrid mode for two spells?
The engine rolls two full phrases and then merges them word by word: for names with more than one token it swaps the last significant term of the first for the counterpart from the second; for single-word names it blends the two internally (the front half of one, the back half of the other) to create a new word that neither roll alone would have produced.
