How do you reroll a riven mod
To reroll a Riven mod in Warframe, go to your Orbiter’s Mods station, select the Riven, and use the Cycle/Reroll option with Kuva as the cost. You then choose whether to keep the new roll or keep the old one.
How it works
- Rerolling changes only the Riven’s stats, not the weapon it applies to, its rank, polarity, or Mastery Rank requirement.
- Each reroll costs Kuva, and the cost increases over repeated rolls up to a cap.
- If the new stats are worse, you can reject them and keep your previous roll.
Practical steps
- Farm some Kuva first. Common sources include Sorties, Kuva Siphons/Floods, Kuva Survival, and some Nightwave rewards.
- Open the Mods terminal in your Orbiter.
- Select the Riven mod you want to reroll.
- Click the Cycle/Reroll option and pay the Kuva cost.
- Compare the new stats and confirm the one you want to keep.
Quick note
A fresh Riven may be veiled, so you usually need to unveil it with its challenge before rerolling stats becomes useful.
TL;DR: get Kuva, open the Mods station in your Orbiter, pick the Riven, reroll it, and keep the version you like best.
