I have stop doing the Manyu Daily (feast of the power spirits) weeks ago. I prefer doing 12-5 or 12-4 (for a fast run) to get amply and the chance for a raid boss or a secret garden.

The daily Manyu map cannot gives us amply, or a chance for equipment seed (raid boss), which are the 2 others options to improve our girls. I also find the event really good, the 80 maps gives us a lot of cash, character seeds and a very high chance for SG and/or Seedy Seed boss. You can also get amply from that map.
