Most efficient dungeons for Moogle Tomes May 2021?

I tend to go back and forth between Praetorium and World of Darkness while interweaving my Nier weekly clears and daily MSQ roulette and Alliance Raid roulette for leveling RDM to get Moogle Tomes. Which I do know is not the most efficient method. Praetorium is chill, but World of Darkness has my favorite mechanic in the game, going into Cerberus's stomach.


So I am asking you all, which duty has been most efficient for you? Has anybody found the fastest way to get Moogle tomes?

Castrum and Dun Scaith both give 14. To me, Dun Scaith seems like it would be very efficient if you get a party who knows what they are doing, but it would be a gamble with randoms though. Dun Scaith is the one raid that either goes to hell, or goes exceptionally good. There is no middle ground. I tend to be good at it.

What have you all found to be the most efficient way to grind Moogle tomes?

E1n or E2n premade parties with 1tank/healer and 6 dps can be cleared in about 3~4 minutes for 3 tomes a clear, PVP is 6~10 for at most 15 minutes of playtime, and Hades EX for 10 tomes per run depending on how quickly you can clear.

I use praetorium. Leveled SAM from 51 to 60 in three days in prae, and I’m usually doing other stuff while there anyways (drawing, watching tv, doing laundry, eating or making dinner). So I’d consider personally, prae to be the most efficient. Least amount of effort, 20 mogtomes, and I get to do other stuff for 80 percent of the run.
