Basically, make sure to have 1600 sol tome + 20K GC seal when you start the Zodiac Brave quest. This way you will be able to do 3/4 of quest at once.

For example:
- Ponze of Flesh
- Labor of Love
- Method in His Malice

Along the way of collecting drop from 3/4 quests, you will use the next 1600 sol + 20K GC to buy the 4th quest (A Treasured Mother) and then you can do all the 4 quests.

Then you need to find yourself a ritual before exiting the dungeon, everyone seems to have their own drill. I like to turn off my monitor and speaker upon the exit then come back later for a surprise. Some does gentleman pose in real life for lucky drop.
