Preparations - Be in True Ending route - Party level average must be between 70s to 90s - Party setup: Noire, Peashy, Rom, and Plutie - Noire and Plutia must have the strongest weapon she can equip at the moment - EXE gauge should be at least 2 - Final Fantasy discs (Godly Game discs)
How to do it: To get 150k EXP, you need to fight the Cat Squirrel Riders, which is also a Quest objective available. To spawn Cat Squirrel Riders, send scouts to Metroid Shelter with the flag in 'Break' state, and make sure that one of them can change the positions of the enemies. If you have done right, the dangerous enemy in the dungeon will be 'Risky' enemies. Cat Squirrel Riders are spawning in the second area of Metroid Shelter. There are two spots for them lurking in the second area, so approach whichever you want to.
How to battle them:
1st turn: Make sure that Peashy's AGI is faster than Noire. Once the battle starts, command Peashy to use Power Up on Noire.
2nd turn: Make sure that Noire is second fastest. Once her turn starts, use HDD, then use the Infinite Slash. To make the Cat Squirrel Riders die in the next turn, the damage should be 150000+ to each one of them.
3rd turn: If this turn is Plutia's, use Stress Release! on the enemies. The damage should be more than 60000. If you done correctly, the enemies will be defeated this turn. Winning the battle will net you 150k EXP.
4th turn (backup): Should Plutia is unable to defeat the remaining Cat Squirrel Riders, command Rom to use her HDD form, then use Northern Cross. Conversely, you can immediately use Northern Cross without changing to HDD.
After the battle: Refill your SP by using Rom's Refreshments skill in battle against normal enemies, or use SP restoring items. Should either Plutia or Noire levels up, it is not necessary to restore back your SP. After that, approach the other Cat Squirrel Riders spawn and fight them. Wait for them to spawn back in the area, and repeat the process.
This battle is also useful to get the 100 hits trophy as well as 100000 damage trophy. It is also useful to get your Lily Rank to increase with discs with Harem chips, as you might spend a lot of time in this spot to get your party members level to 99.
So with XP up, too, that's like ~200k in a minute, so it's actually about equal to the Planeptune Alley method. Double nifty.
Can't use scout to raise the EXP since you're using them to spawn the Cat Squirrel Riders already. You need to use EXP Up chips instead. --- W> Mugen Souls Z, Date A Live, Neptunia High School v3 PSN - PrimulaSinclair
So, the lily EXP up is 33+% EXP increase? I didn't really bother to check but I actually thought it was lower than that. --- W> Mugen Souls Z, Date A Live, Neptunia High School v3 PSN - PrimulaSinclair
