i recently learned about something called a witch gun. Let’s make this happen!
Also, how about a non-concentration effect….
Witch Gun
1st-level enchantment
Casting Time: 1 action
Range: 30 feet
Components: V, S, M (a metal tube of blasting powder and spices )
Duration: 1d6 rounds
Choose a target in range and make a ranged spell attack. on a hit, the target is struck by the witch gun. Roll a d6. For that many rounds, the target must roll a d4 and subtract the number rolled from the attack roll or saving throw.
At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature for each slot level above 1st.
