Rich Vein respawn times
If I remember right 23 hours.
RIP City of Heroes
They reset with the daily. There is also a 6 hour timer as well. If you mine a node at 1 hour before reset, you’ll have to wait another 5 hours after reset to mine it again. If you mined it 6 hours before reset, it should be ready to be minded again at reset.
Actually, I just realized this immediately after posting. I’m referring to T6 nodes specifically and not rich. I’ll look up the timers.
“Some nodes take approximately 23 hours to reset, including permanent rich metal veins, node farms, and those that produce Orichalcum Ore or Ancient Wood Logs.”

I disagree with the last part about Orichalcum Ore and Anciebt Wood Log nodes as they are not on a 23 hour timer. I’ve minded them all in the morning before across all of my characters and then was able to right after reset which was obviously less than 23 hours. This is unless they’ve changed it within the past year.
