First, you need to get your hands on a food called "Apple Ice Cream". The earliest you'll get this is in the inn at Ravennue village. Buy and eat one to learn the recipe, then go back to Bose's market to buy as much of the ingredients as possible. One of each ingredient equals to about 80 something mira while the ice cream itself can be sold for 125 mira. If you mass produce 99 of it and sell it back to the market, you can make 4000 something
mira per 99 ice creams sold. Repeat until satisfied and when funds start to drain. No more selling your precious sepith!
Two rather silly references:
After defeating the final boss and now wander the streets of Grancel, if you should talk to two people around town, you'll encounter a reference and a short 4th wall breaking session.
The reference requires you to talk to a man in front of the Inn in town, taking a picture of his daughter. Talk to him and he'll tell his kid to smile and say "Fuzzy Pickles!". Get it? This is a reference to the random photographer from the old cult favorite game of EarthBound!
The fourth wall breaking is found in the Liberl News building by talking to Dorothy at the desk. She will mention being legible to the "Fuelitzer" prize. Estelle questions that and asks if she meant the "Pul-" until Joshua stops her abruptly by saying "Shhh! You want to get sued?". It's an easy guess to think she meant the "Pulitzer" prize.
Simple and 2 different ways to flash farm Sepith's:
A few notes, maximum Sepith per battle is only 70. This will not go any higher.
Shinning Pom's are your only target. Finale Chapter Pom and Prologue Pom.
ALWAYS PRE-EMP STRIKE a pom. If you begin without it 95% of the time they will flee.
(1)Finale Shinning Pom - Shadow Spear Method 20% instant kill.
Before entering the Arena, that is the ideal time to farm it. You can have 4 party members that can cast multiple shadow spears the odds of getting 1 pom are much higher. Finale Pom yields 70 Sepith per kill. You need only 1 spear of instant death, killing the rest will just waste time.
Side note: This is also an effective way of power leveling if your are under level. Final Chapter pom gives out a lot of exp.
Prologue - Normal Hits
(2)On your 2nd Play through you will be most likely Level 35-40+ allowing you to 1 hit poms. You just need to have the right quartz Action 3 and Hit 3 is needed and of course a PRE-EMP STRIKE always. This method though will require you to kill all 3 poms, since Prologue poms yield only 20 per pom = 60 Sepith per battle if you kill them all. This method is what i personally use around 1 hour mark and i easily get 9,999 max Sepith.
