Chill Touch, Ray of Frost are cantrips.
Chromatic Orb Ray of Sickness and Witch Bolt are level 1.
Eldritch Blast, Melf's Acid Arrow, Ray of Enfeeblement aren't Sorcerer spells at all.
Only Scorching Ray is a sorcerer attack spells higher than level 1... hardly something you can base a build on... hmm.
Plane Shift is the only one on the sorcerer list. While it does qualify, it is a level 7 spell, and it denies you the enemy's loot.
Okay, so then I realize that the ability of Wild Mages to attain advantage on attack rolls is in practice useless, at least for now, before any splat books. There simply isn't any spells that use attack rolls a sorcerer can use.
Thanks anyway.
