This is a great guide.
I'm too lazy and parsimonious to use converters an so on, but I went well past 100 mil recently.
Don't do what I did, it's super ineffiicent. ;D
I rolled a Kinetics Defender, because people love Speed Boost and Fulcrum Shift and I get those earlier than on a Controller.
I sold all salvage for 1 inf.
I crafted rare recipes with what salvage I had on me or in our base bins (I run a 2-player SF with an irl friend), then listed then either for 1 inf or for x11,231 if they sold for more than 1 million.
Once I got to 50, I just ran ITFs, LRSFs, Hami Raids, and farm runs and sold the drops.
If you play on Excelsior, you may have seen my "Still not a Centriole!" after getting a Hami-O or a Synthetic one. They get dropped on Market if we don't need them for builds.
Any purple picked up on our farm runs that wasn't going to get used in our builds hit the market, generally getting us 20 mil or so.
Reward Merits have been unspent so far. I am currently at 1,639 Reward Merits. Hoping to pass 2,000 by end of week. Once I hit 4,000-5,000 I'll spend a bit.
Not sure if this is "a lot", but I've converted all Vanguard Merits into Reward Merits, and the odd Empyrian into them, for rounding purposes. I'll have to do this today to get to 1640. I detest unrounded numbers.
If I need a "quick hit" I just buy an ATIO proc with reward Merits (100 is trivial, it's 2 Positron TF, 1 Synapse and some change) and that generally gets me 11 mil or so.
I used a bunch of my inf to finance my friend's Stone Melee/Invuln Brute, King Stone Wolf, and still have tons left over.
I've long passed the point where I got upset at people with tons of inf. There's just too many ways to get it. And once you hit 50...it's an endless tap of income.
I have been super lucky on drops. I got a Panacea proc killing Hellions, an Unbounded Leap + Stealth killing Jurassik.
ALL PvP IOs I cannot use on my Ill/Emp or Stalker get crafted and sold as well.
Since I'm lazy, I also drop millions (super inefficiently!) for pretty meh stuff like Titanium Coatings and so on.
Edit. I am running on Single Origins only, with my only IO's being a Karma, KB protect and a Karma Defense on my Defender.
I might have a Numina proc on him too. Currently at Tier 3 on all Incarnate stuff because S o l a r i s is a great leader. :-)
And the money still rolls in!
(I don't consider myself wealthy ingame, that will happen once I hit 600,000,000 inf or so, which would allow me to get most of a build off the Market.)
