This question already has an answer here:
I've been playing a level 9 Stone Sorcerer, and I was about to multiclass 2 levels into paladin when I saw that when you prepare your paladin spells, you prepare spells that fit with the level of spell slot you have. Because multi-classing essentially blends your spell types together into a tasty smoothie (for example I already know I could use a 4th level sorcerer spell slot for divine smite if I so pleased), does this mean I could choose Paladin spells like Geas and Destructive Wave to be prepped? Or am I still locked as to what I can prepare with my paladin spells?
Thanks for the help in advance.
