Build can be used for all missions, both Steel Path and Normal. Spores scale fast enough for Steel Path, but not fast enough to kill the count for normal missions. Blue Archon Shards for Energy and Yellow for Energy Orb Efficiency are recommended, with Reds for duration a commodity. For extra survivability, blue Archon Shards for Armor can also be used.

Use Breach Surge and Toxic lash as a combo to spread spores, and Miasma to spread spores even more. Breach Surge and Miasma scale their damage higher, resulting in faster scaling, and Molt Augmented will scale the strength to accommodate Steel Path enemies.

Recommended Weapons: [Kuva Bramma] to spread the spores, [Kuva Brakk] for Boss Enemies, and a Crit [Kronen] to pop spores fast.

Companions: Panzer Vulpifila for more spores, but overall Companion isn't needed (I use [Helios] for extra scans)
