This guide will let you know where to get the Hammer shot and Blaze in Warframe.
The Hammer shot, and Blaze can boh drop as a reward for completing nightmare missions on certain planets. The certain planets you’re going to be running the nightmare missions on are Mercury, Venus, Earth, and Mars) unless the mission is a rescue mission.
If the mission type you are running is a rescue mission, you can run that type on any planet; however, you need to make sure that you raise the alarms. And don’t kill all the wardens; save the hostage as doing that will give you rewards from the rotation reward pool, where Blaze and Hammer shot can drop from. They also have fairly low drop rates, so it’s likely to take you a bit of time before you get the mods to drop.
It’s important to note that if you run a nightmare mission and don’t get the mod, then you’ll have to wait until the rewards refresh for that mission as you can’t get rewards from a nightmare mission after you’ve done it already (the mission rewards resets every 8 hours).
