So I made a table.
|1||generic change/sense||10 feet||2d6 turns||30 feet|
|2||control||20 feet||2d6 turns||30 feet|
|3||dispel||30 feet||4d6 turns||30 feet|
|4||create||40 feet||4d6 turns||60 feet|
|5||soul||50 feet||6d6 turns||60 feet|
|6||death/major change||60 feet||6d6 turns||60 feet|
The spell creates a wall of thorns? "Create" is a 4th level effect, the wall will be 60 feet wide; right now, the duration would be 4d6 turns. If it made existing thorns grow into a wall, it's a change of state spell, which is essentially permanent until something else changes the state again.
The spell swaps the soul of the target with the soul of the caster? 5th level, 50 foot range, lasts as long as the caster concentrates or 6d6 turns.
Because of the simplification of the spell patterns, many spells will change, but there will be some notable dead-on copies of spells from the original game, because that's how I derived the simplified rules.
Still need to do the cleric version, and maybe the druid and illusionist versions as examples of custom spell lists.
