Independent Research: A wizard also can research a spell independently, duplicating an existing spell or creating an entirely new one.
I've read the entire magic chapter in the PHB, but I've clearly overlooked something. Let's say my wizard has already selected his two new spells for leveling. Now he wants to research another existing spell, say, scorching ray. How long will that take? How much will it cost? Does it require a spellcraft roll or some other roll to determine success? The PHB sends you to the DMG for rules for researching spells, but the DMG only has guidelines for DMs adjudicating new spells. What am I missing?
