School transmutaion; Level Sorcerer 3
Casting Time 10 minutes
Components V, S, M (a small bag with dry leaves and malachite dust), F (a silver-lined mirror worth 50 gp)
Casting this spell allows you to gain additional spell slots for later use, or prepare spell slots as supernatural abilities. Pick one of these two versions when the spell is cast.
Gain Magic: You prepare up to two additional levels of spell slots. A cantrip counts as 1/2
level for this purpose. You cast these spells normally.
Innate Conversion: You convert any spell slot of 2nd level or lower into a supernatural ability. You can use this once per day, and the spell functions normally except that when cast it is considered to be a supernatural ability.
These effects fade after 24 hours (if not used).
This is, of course, a Sorcerer equivalent of the Wizard-only spell mnemonic enhancer. So much of this game has gone into designing Wizards well. It’s going to take a lot of digging to get Sorcerer out of his hole.
In any case, the effects of this spell are somewhat weaker than the Wizard version, and is thus a 3rd level spell. It grants Sorcerers an equally interesting choice and the opportunity to do some things not normally available.
All without messing with the “spells known” table, much as I might like to do so.
