Pass Without Trace is level 2. It's not a Wizard spell though.
Still pretty insane, makes Druids and Rangers pretty much the best at stealth, poor Rogues can't compare until way later.
For my system, I did it so the spell let you roll Spellcraft, divide by 5 and that's your bonus to the skill.So much of the spell list could be fixed by utility spells simply giving a bonus to skill checks (this would also fix skills at the same time).
Pathfinder 2e has something similar, but for items.WotC would absolutely never dare to add any narrative-type powers, but I'd like to see a wizard subclass focused on being extremely well prepared. I'd like to see an ability like this, that would be exclusive to a particular subclass:
Always Prepared: Once per day you may recall that you have actually prepared, ahead of time, exactly the right spell for the occasion. This is not an action. When you use this ability you memorise one spell from your spellbook (it was technically already memorised).
Edit: Admittedly it would be OP, but you'd balance that by taking something away from elsewhere.
That's what gave me the idea in the first placePathfinder 2e has something similar, but for items.

Cost the Price of the chosen item
Requirements You haven't used this ability since the last time you were able to purchase goods.
You regularly create convoluted plans and contingencies, using your resources to enact them. You take 1 minute to remove your backpack, then carefully remove an item you hadn't previously declared that you purchased—you intuited that you would come to need the item and purchased it at the latest opportunity. The item must be a (common) piece of adventuring gear...
Between borrowed knowledge (to get proficiency) and enhance ability (to get advantage), you could cover the cover skill bonuses needed, and drop a good portion of utility spells if you wanted to go that route.So much of the spell list could be fixed by utility spells simply giving a bonus to skill checks (this would also fix skills at the same time).
To tweak this a bit...Always Prepared: Once per day you may recall that you have actually prepared, ahead of time, exactly the right spell for the occasion. This is not an action. When you use this ability you memorise one spell from your spellbook (it was technically already memorised).
