I recently started reading through the Shannara books by Terry Brooks, and it got me thinking about how the notion of the wishsong would translate into a system like D&D.
My (very) rough idea right now is a sub-class of sorcerer who can learn spells from any school or class as long as that spell uses only verbal components.
I found a pretty good tool on a site that let me filter to get a list of all verbal-only spells. Level-wise, the list looks reasonably well-distributed and has a decent mix of combat and non-combat spells. That said, I don't have an encyclopedic knowledge of D&D spells and my experiences with the Sorcerer class is limited.
Would these spells be seriously unbalanced when combined with the class features of a sorcerer?
To be clear, taken as a whole, this list will probably still be too limited and will require adding in some additional spells to round it out later. My primary concern is identifying any game-breaking outliers before I start making further changes.
