It is Riven disposition change time in Warframe. The Empyrean update has brought a substantial number of changes to Riven dispositions, which are mighty mods in Warframe. Specific to a weapon, you can reroll these until something compelling emerges. It is safe to say if you are searching for the Riven changes, that you are aware of how Rivens work in Warframe. Let’s get straight into a big list of all the Riven disposition changes from Warframe’s recent update.

Remember, if the number has become smaller, it means Rivens for that weapon has become rarer. If the number has gotten bigger, then Rivens for that weapon are more likely to drop in-game.
