Assuming one already read Stormlight, what order should the Cosmere books be read in?

[Dev she/her]

A friend of mine just finished Oathbringer, and I want to give him some other Cosmere books to read. I've been reading them as they came out for so long, I'm having a hard time thinking of what order they should go in, especially now that he's already finished Stormlight. Publication order, Elantris-Mistborn-Warbreaker-Arcanum? Or start with Mistborn because it's bigger, or start with Warbreaker because it's relevant?

It's so weird trying to figure this out, because I've just been so deeply into all the realmatics and cosmere stuff for so many years, it's strange to think about someone who doesn't know any of it and where to begin. He was like, 'What's up with that Wit guy?' and I couldn't think how to answer because Hoid is just. . . Hoid.

If they've already cleared Stormlight (Including Edgedancer?), the next step to me would be Warbreaker on the logic that it's the closest direct/relevant tie and will have things he recognizes, and was entirely conceived to provide backstory for those character's appearances in the proto-Stormlight Archive. 

 

After that it sort of depends on the Friend and their reading patters, Id focus on whatever you think will draw them in the most.  If you think they might not stick around for all of mistborn (unlikely if they finished SA) maybe give them Elantris or Emperors Soul and some of the other sorts.  If it's the cosmere realmics that will float their boat, give 'em Mistborn Era-1 and Secret History.  If they need a fun, pulpy romp, give em Mistborn Era-2, but only if you had to because it entirely spoils the Era1 finale to read them out of order.

Also, dont forget the Graphic Novels, White Sand is beautiful.

Either Mistborn Era 1 or Warbreaker. Warbreaker has more direct major character connections, but Mistborn "The Final Empire" is a better book (Warbreaker is good though) and Era 1 eventually dives into the nature of the Shards a lot. 

I would go to Elantris last as it has the fewest overt Cosmere references and Brandon's writing has grown a lot since then.

Best to read Mistborn, if you ask me. It explains a lot and gives that Stormlight-quality.

[+Invocation]

Mistborn or Warbreaker, probably. Mistborn because of few Stormlight characters and an interlude, Warbreaker because for the same reason, really,

I would suggest Warbreaker after Stormlight. It gives context to a number of characters in Stormlight and a nice self contained story. After that though I would suggest Mistborn.
