Addendum: Minor Spellcasting House Rule

Back in March I posted a house rule concerning "Minor Spellcasting" - where a character gains a small number of spells from their race, a feat, or other source, and where they also gain spellcasting from their class, the spellcasting ability from the minor ability is overridden by that from their class.

The addendum to that rule simply takes things a little further: the spells gained from Minor Spellcasting are simply added to the character's spells known (and considered "always prepared" in the case of prepared spellcasters such as Wizards), and slots added as appropriate.

For example, a 5th level Tiefling Sorcerer knows 5 cantrips and 6 spells. They also have 4/3/2 slots of each level. As a Tiefling, they also gain the thaumaturgy cantrip, hellish rebuke (as a 2nd level spell), and darkness (another 2nd level spell).

As a consequence of the house rule, they now know 6 cantrips and 8 spells, and have 4/5/2 spell slots of each level.

Finally, at various times the character has the ability to switch out some spells for others. This includes those spells and cantrips granted by the Minor Spellcasting trait.

It's worth noting that this does mean a small increase in flexibility, and consequently power, for such characters. But it's such a minor boost that the reduction in bookkeeping makes it worth it, at least for me.
