Yeah those 3 are human path. Once you get to psychoponics you find a thing that lets you scan typhons which unlocks the 3 typhon trees. Scanning different typhon unlocks different abilities, and scanning more of the same unlocks higher tiers of those abilities. But unless you are going for achievements then you should only get 1 or 2 typhon abilities you like then dump the rest in human abilities until they more or less run out.
That’s fine. Weapon upgrades are plentiful, especially when you find the fabrication blueprint. Oh and there’s also a neuromod blueprint.
Better start farming those exotic, mineral and synthetic materials.
