My favorite class in DnD is the up close wizard/warrior. I like hitting with spells and magic at the same time. I think we can do that if we play with some boons and banes just like two-weapon fighting…
You can cast a spell and perform a one-handed melee attack in the same turn. If you attack the same target with both, the melee attack suffers two banes, and the spell attack suffers two banes. If the spell requires a challenge roll, the target gets two boons.
If you target two different targets, you suffer three banes to the attack roll for the spell and the melee weapon. If the spell requires a challenge roll, the target gets three boons.
