Adaptive Lightning

You create a floating, electric weapon within range that lasts for the duration or until you cast this spell again or buff your current weapon with it. When you cast the spell, you can make a melee spell attack against a creature within 5 feet of the weapon. On a hit, the target takesforce damage equal to 1d8 + 1d4 lightning damage and they will have to make a constitution saving throw. As a bonus action on your turn, you can move the weapon up to 20 feet and repeat the attack against a creature within 5 feet of it. The weapon can take whatever form you choose.

When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for every two slot levels above the 2nd.

When the class level is 5 then there is no need for the d10 random effect table.
