In this guide, you will come to know how to get the Cleaving Whirlwind in Warframe. Go through the guide and follow the instructions carefully to get it.
Cleaving whirlwinds can drop as a C rotation reward from completing the spy mission on Lua, and you have to crack all three vaults to get the C rotation rewards.
It is recommended to have frames like limbo or nova, so you can get around the vault easier without worrying so much about lasers and stuff.
It has the lowest drop change out of the mods/items in the C rotation reward pool, so it may take a few runs before you get the mod.
