Used a combination of the following -
1: caer blaidd Farming - First you shape your atlas for Vaults and Shaped Burial Chambers. So no other T8 or T9. Then you chain these for days. They are cheap as chips and there is an infinite supply of them. I paid no more than 3c per map. Each map I would get on average 2 - 3 Vaults as well as 2 - 3 Shaped Burial Chambers. The vaults were selling for 40/10 and the Burial chambers the same. That is guaranteed profit. Then you take into account the nice IIQ and IIR on the map itself 150%/150%. I dropped a bisco's, 2 Shavs, exalts, etc while farming the maps. This was by far the best money maker for me this league.
2: Uber lab - Yes very obvious I know. However I have never run lab more than was required to get my ascendancy points up until now. The money you can make from lab is sickening. I got numerous T1 enchants, I got 2 x 3 Molten strike proj, 4 x Barrage proj, 3 x Volatile dead +1, Etc so as this is obvious to some, for you those of you unsure if lab is worthwhile to farm, is sure is. Over and above the enchants the chests are great!!! The number of 20% gems I got with levels is insane! Drops those in a 20c tab and they sell for days.
3: Flipping - Also obvious, however I didn't bother with difficult things this league. I picked 6 distinct items and flipped these only. 16% IIQ Sadimas, set your whoop up at 1c max buyout, 100's come up at this price, resell any day of the week for 10c. Healthy Mind jewels, with the new RF Mana Guardian build. The 20% jewel sells for around 20c. The lower rolls for an alch, 85% of people just toss the 20% up at an alch, ez flip. Etc. If you guys want more on this let me know.
4: Div card turn ins: I did at least 80 sets of "Pride before the fall" this league, it is guaranteed profit of 20 - 30c if you get a bottom fire damage roll, and up from there. I only managed to get 1 "+1 max res" corruption but that netted me 20ex profit. Also There are other div card sets with guaranteed profits let me know if I should bother to expand on those.
5: Splinters - Flipped Chayula splinters, bought tonnes at 10-22c and resold at 10-30c.
None of this is ground breaking stuff. Just thought I'd share.
