Mediena and Yshtola have AOE abilities (Cosmo Plume and Foul). Use them to defeat all enemies in these quests.
Mediena is the best. If you are a F2P player and don't have Mediena, use Yshtola instead. Yshtola however need to have enough level and magic stat to defeat enemies with 1 attack.
1) 8 enemies (any enemy has roughly 85%-90% of drop a chest)
2)Any chest has roughly 20% of cointain a faint memory
3)energy efficient cz u get 1,4 memory/6 rng
Ps u need mediena one shot one row of 4 enemies and a friend mediena to one shot the other row of 4 enemies

I did a lot of test
I will suggest story 2-2-8 (the royal bloodline)

I noticed this stage when I was farming for some crafting materials. Usually I get 6+ chests every run. Not to mention other "more than 6" enemies maps give me only 2-3 chests. Thanks for sharing this!
idk if this is considered efficient, in a sense that you will be paying attention most of the time yes, but in terms of auto repeat and letting it run, not so much
Kronoa is correct that 228 is best chance of fbm/nrg spent.
However 133, 221 are still viable choices if you are also looking to get xp & jp too, in as quick a time(real time) as possible, and you are not worried about nrg spent.
