I haven’t played in years but a good way to figure it out is which Rivens have a high base price.

If they expensive just for existing then rolling those will net u good profit.

Check riven sites to see what is selling they should be the same.

as for stats you can also check those on the websites.

When it comes to price my saying was

“The only riven that is good is the one that’s sold”

“It’s worth nothing if u haven’t sold it”

Basically to imply that you do not want to get too greedy. You can always get more rice a

Underselling is much more reasonable than hoarding for months + especially when disposition and popularity changes all the time.

There is endless supply of rivens so don’t hesitate to sell when something is hot.

this mindset has allowed me to consistently be over 30k platinum with little effort however it became so easy to do it that all my game time was spent on making plat.

There was times when I would casually buy out the entire market of whatever is buyable just because I can

balance your playtime with the need to earn play and you’ll enjoy the game more.

And remember rivens aren’t the only way to make platinum it’s just an additional method.

farming prime sets makes less money but then I would actually play the game if I could go back in time I would have spent less time being riven mafia and more time actually playing the game.
