Bonus spells

Let us override a character’s class spells known and prepared limits if we want.

We should also be able to add spells from the SRD that aren’t in our class spell list.

This would not only be useful flexibility in general, but better match the rules of the system for many classes.

For core rules examples:
Clerics and Warlocks get bonus prepared spells that don’t count towards their prepared spell limit based on subclass, some these are spells that aren’t on the classes base spell list.

The Lore bard gets 2 known spells from the cleric, mage, or druid spell list.

Basically there are 2 components:
The ability to add spells from the SRD outside your class list.

The ability to mark spells (known or prepared) as ‘bonus’ so they don’t count toward normal limits for you class. (or just the simple ability to override and extra spells)
