I am currently DMing a campaign where there is a wizard with the Identify spell, the bane of my existence.

Identify allows him to learn the properties of literally every single item the party encounters. I understand that Identify uses resources (either spell slots or time), which is relevant in a dungeon with wandering monsters, but out of perilous situations there are not many drawbacks.

I am going to give the characters a really cool artifact sometime in the future, with a lot of mysterious characteristics that I want them to find out slowly. One action, and all the properties are discovered.

I am creating a shop called Ocean's Potions In which a water genasi wizard creates a whole bunch of random potions in pairs, so the PC's can drink one to find out the characteristics are, and then use the other sister potion when it is relevant in the future. There will be a lot of cool, beneficial, and random potion effects that will effect them when they try them. However, Identify can let them choose the best in one action, and let benefit from the effects twice.

I understand that spells should do what they say they do, but how can I get around this spell ruining everything?
