In this guide, you will learn how to farm for Nano Spores in Warframe. Go through the guide and follow all the instructions to farm them.
You can usually farm nano spores from 1 of 2 locations: Piscinas on Saturn and the Cambion drift on Deimos. Piscinas is more or less your standard survival farming mission, so you can bring Nekros to help with loot drops.
Once you get into the Cambion drift, for the most part, all you have to do is go around the open world looking for rolizer infested cysts. They can drop nano spores; you can find the most cysts in caves on Deimos, so make sure you hit those caves before you leave Deimos.
