I’ve done a fair bit of industry in my time in EVE Online. Ran a HiSec/LowSec industrial corp, managed industrial activities for a FW corp, did my own production for profit (tech 1 ships and rigs). But one thing I never did was invention because a) it seems terribly over-complicated and b) back in the day you could only do it at a POS, and everyone I knew who did it had a large tower and something like 10+ “invention alts”, and they needed that many to be profitable due to chance of failure and overhead of running a POS.
But now we have Citadels. I am taking full advantage of Citadels in researching various BPOs for future use. But I was thinking of dabbling in invention. I have 4 characters which will be available to train anything I need after their current queues are completed in a couple of months. Is invention on a single character profitable in this age of Citadels? And what’s the best way to go about it? Buy the materials off the market? Farm the materials? Build the materials?
