A perfect build for 8 waves of solo SO. With max range and efficiency, you can clear the whole room with your Spores and Miasma. I use this build to help my friends and people in my clan to level up their warframes or weapons.
Notes:
Don't just spam Miasma. Use Spores on one enemy first, then use Miasma only once. When new enemies spawn, use spores on them and then Miasma, rinse repeat.
Since the strength of this build isn't too high, it's recommended not to use this build in ESO. Also, viral damage isn't very effective toward the infestation, so you wouldn't want to encounter the infested on high waves.
Enjoy!
