I started a Pathfinder CRPG a few days ago and one of the classes is specifically designed just to do that. I was tempted to choose it but it had like the highest class difficulty and it’s my first time playing so I played it safe and just went with a regular ol’ sorcerer.
Its mainly because it makes no logical sense. You van just put the sword in the shield hand then cast the spell it would not even be that hard.
It’s almost impossible to do that in a high stress environment without dropping the weapon, and if the shield is a buckler or a viking shield it’s completely impossible due to how you hold the shield. In any case you make the shield unfit for blocking while holding the sword.
If you want to throw spells you should do as the romans with a small sword with a scabbard on the sword arm side and sheathe the sword to free the hand
