This guide will let you know how to get the Frigid Blast in Warframe. You will need to follow the simple steps in this guide to get it.
Frigid Blast can drop as a C rotation reward from spy missions on the Kuva Fortress. To get the C rotation rewards, you will need to crack all 3 Data vaults to have a chance at getting the mod.
It is recommended to have frames that can teleport or get past laser walls, limbo, nova, etc.
It shouldn’t take you too many runs before you get the mod unless your luck is bad.
