Question about book 2

I'm in the middle of the book atm and just had a question

So right now, the troops are outside of luthadel and the group is being backed into a corner, etc. A seemingly large part of why Luthadel is so contested is because everyone believes this is where the Atium that the lord ruler mined for decades is at.

Aside from the effect that atium gives to mistborn/allomancers of being able to see a few seconds into the future, do we know of atium doing anything else so far? I guess also aside from making whoever finds it the richest region in the world too.

These are both valid enough reasons for luthadel to be so contested. Whoever gets ahold of said atium will be in power for God knows how long, especially because kelsier made atium unminable for the next few centuries to come. I'm just trying to make sure I know all of its uses since an alternate title to this book could've been "the hunt for the atium" at this point lol
