D&D 5E Spell Creation System?

[77IM]

Has anyone found or developed a more formal system for PCs to research spells? I'm looking for something with a bit more guidelines than the DMG (which has less than half a page creating new spells) but not so detailed that it takes an hour just to understand the system.

I modified the rules found in earlier editions of Shadowrun Street Grimoire. It gave me a set of rules for each type of spell. Means some spells such as wish can never be created or used by a character. Creates a vast difference in similar spells, you can have 100+ different fireball spells for example.
