I’ve been using a gathering scenario for timed nodes and I made it spiritbond effecient. It’s able to extract materia every 2-3 nodes.
I leave it on while I sleep and turn if off when I leace for work (about 6 hours). Which comes to tons of materia.
Sell and profit. Made 20 mil in 10 days or so. This is also when I stock some materia for myself for future pentamelds.
You can find the scenario in the forums.
Would you mind sharing your scenario? I’m having trouble finding one that is optimized for spiritbond
