Gnome:
Darkvision: You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light.
Gnome Cunning: You have advantage on all Intelligence, Wisdom, and Charisma saving throws against magic.
Artificer’s Lore: Whenever you make an Intelligence (History) check related to magic items, alchemical objects, or technological devices, you can add twice your proficiency bonus, instead of any proficiency bonus you normally apply.
Tinker: You have proficiency with artisan’s tools (tinker’s tools). Using those tools, you can spend 1 hour and 10 gp worth of materials to construct a Tiny clockwork device (AC 5, 1 hp). The device ceases to function after 24 hours (unless you spend 1 hour repairing it to keep the device functioning), or when you use your action to dismantle it; at that time, you can reclaim the materials used to create it. You can have up to three such devices active at a time.
Sage
Researcher: When you attempt to learn or recall a piece of lore, if you do not know that information, you often know where and from whom you can obtain it.
Wizard
Arcane Recovery: Once per day when you finish a short rest, you can choose expended spell slots to recover. The spell slots can have a combined level that is equal to or less than half your wizard level (rounded up), and none of the slots can be 6th level or higher.
School of Conjuration
Conjuration Savant: The gold and time you must spend to copy a conjuration spell into your spellbook is halved.
Minor Conjuration: You can use your action to conjure up an inanimate object in your hand or on the ground in an unoccupied space that you can see within 10 feet of you. This object can be no larger than 3 feet on a side and weigh no more than 10 pounds, and its form must be that of a nonmagical object that you have seen. The object is visibly magical, radiating dim light out to 5 feet. The object disappears after 1 hour, when you use this feature again, or if it takes any damage.
Benign Transposition: you can use your action to teleport up to 30 feet to an unoccupied space that you can see. Alternatively, you can choose a space within range that is occupied by a Small or Medium creature. If that creature is willing, you both teleport, swapping places. Once you use this feature, you can’t use it again until you finish a long rest or you cast a conjuration spell of 1st level or higher.
