You brandish the weapon used in the spell's casting and make a ranged attack against each creature within a 15’ line, using your spellcasting modifier for attack and damage rolls. On a hit, each target suffers the weapon attack's normal effects as if you had made a normal melee attack.  
At higher levels: when you cast this spell using a spell slot of 3rd level or higher, the spell's range increases by 10’ for each spell slot above 2nd. (25’ at 3rd level, 35’ at 4th, etc.)
