Definitely get that FSD range increase, it's really easy, Felicity Farseer just needs some items that you can buy to unlock her services. Here's the ingredients list:Also should I grind engineer/guardian FSD before I go Exo? I'd rather do it before if it makes it more fun less boring doing Exo later.
Increased Range FSD
Grade 1
1 x Atypical Disrupted Wake Echoes
Grade 2
1 x Atypical Disrupted Wake Echoes
1 x Chemical Processors
Grade 3
1 x Chemical Processors
1 x Phosphorus
1 x Strange Wake Solutions
Grade 4
1 x Chemical Distillery
1 x Eccentric Hyperspace Trajectories
1 x Manganese
Grade 5
1 x Arsenic
1 x Chemical Manipulators
1 x Datamined Wake Exceptions
Materials Traders can be used to trade up or down your materials for what you need.
Echoes, Solutions, Trajectories and Exceptions can be had by scanning FDS wakes.
Processors, Distilleries, and Manipulators - I think you can find them in High Grade Emissions signals, or you can earn some top tier materials like crystals from missions and trade for them.
Manganese and Arsenic, either trade up your other minerals from mining, or there are ways of at least getting Arsenic directly, I got mine from The Bug Killer site which is also good fun driving the SRV around chewing up the scenery. Trade the other things you get for Manganese.
You will need about four or five "clicks" on each grade before the next grade unlocks.
