Ah, not sure about rank, but think it was called an “Elite mark.” Think those are weekly, so several hours after spawn makes it not an efficient way. I’m always rolling in poetics, they are partly my Gil making scheme at my current development level (80 combat level, just starting botanist/culinarian). Did a couple of maps, almost gave up on the second one because it bore almost no resemblance to where I eventually found the treasure. Man, the maps in this game really suck.
