Cyberdimension Neptunia: 4 Goddesses Online - Part 009 - The Emerald Mirror
2The part begins at the newly unlocked Hestie Crater with the big sisters, although I swap to the younger ones towards the end of it.
I don't face the boss just yet, but make another run through again (mainly for more Ore for equipment upgrades I get) and then face the boss to receive the Branch of Leanverde needed to make the Purification Arrow, which Compa makes with assistance from Neptune.
The maintenance also finishes and we can go back to Yiear Sea of Trees, so at around the 37:00 mark we head back there.
the Ulgadeus are now gone from there, and a few new enemy types appear, which shouldn't cause an issue.
The Nowaid boss goes down in two stun cycles, the only attack of any concern is the dual laser beam, but it has a fairly short range, and looks like it can be jumped over.
Afterwards Kiria and the Cat Princess reveal what they have been using to gain an advantage. A Cheating Tool.
They then turn into a Cheetah and you have to fight them.
They have a lot of HP but that's about it.
Once defeated the Grim Reaper "rescues" them.
With the Emerald Mirror in hand we now have all Four Sacred Treasures so can go to Tetyu Temple in the next part.
