Witch Spring 2 touts a rather extensive post-game. It shares some commonalities with the previous game, but has also added some more events and scenes.
Unlike the first game, you are guaranteed to enter post-game after you defeat the final boss. After seeing the credits, Luna will return to her original hideout. After she thinks back on how it was because of that cave that she survived the past ten years, you're free to control her. Even though the post-game starts here, if you use the Home spell, you'll still be taken back to the Ice Witch's House.
Robin can be found at the entrance to the Pope's Castle in Vavelia Village. His dialogue will change depending on whether Luna attacked him in Chapter 5 or not.
If you cleared Ludina's side-story, she will appear in the Ice Witch's House. She has a conversation with Luna, but afterwards, she can't be interacted with. (Note: She won't appear if you don't clear her side-story, right?)
When you visit the Black Witch's House for the first time in post-game, you'll have a special conversation with Pieberry.
If you saw all of the Pieberry and Justice events, Pieberry will reveal that she is now dating Justice, suggesting that the "Hope given by love, Love given by hope" ending is the "official" ending to the first game.
After this conversation, Pieberry will no longer be found in her home, and will instead be in Elysion's Temple by her mother's side.
Justice can be found at the entrance to the Pope's Castle in Vavelia Village.
Manil Island is still off-limits even in post-game. However, Luna won't be driven off by cannon shells anymore and has different dialogue with the Warriors blocking the path to the island.
You can find Alflady in Vavelia Village, near the castle entrance. She will have a conversation with Luna, but that's it. (Does the conversation change depending on whether you got her achievement or not? Or will she not even appear if you don't get it?)
While Luna's outfit changes were fixed in-story, you have access to several outfits in post-game. Along with her default and Ice Witch costumes which were seen in the main game, Luna can gain another four costumes in post-game.
The first two in the image can be purchased from Ralph the Merchant, while the other two are gained through events. The third is gained by defeating Aramute in the Mind Room, while the last one is gained by clearing Sara's post-game quest.
Kate the WitchEdit
Before post-game, if you tried entering Ruth's Falls, Luna would retreat from the zone after a brief bit of dialogue. In post-game, the first time you enter Ruth's Falls, you will enter combat with Mullet. It will drop a scale that can be sold for a large sum of money.
Like all other post-game bosses, Mulette can only be fought once. After defeating it, if Luna enters the Falls again, she will comment that the current is too fast and will retreat from the area.
If you try to go to the right of Arua Temple before the post-game, Luna is attacked by pirates and flees because she believes she isn't strong enough to fight them. Return there in post-game, and Luna drives them off using her spells. Afterwards, three chests will be floating in the water. Each chest contains 10,000 Gold.
Continue going right, and you will come upon a cave that Luna can enter. Once you reach the center, you will fight the pirate captain and his men again. After defeating him, you can open more chests that contain more gold.
You can find Livya at Vavelia Road. After you complete the game head to Vavelia Road. Directly in front of the path to Boar path, you can see many steps heading down. after you head down you will see a sewer gate that Luna commented was lose during Jude attack. You will encounter a 9000 HP dark warrior and at the entrance and after defeating him, it is recommended that you heal and prepare yourself to battle Livya. head up to the rocky path and talk to Lyvia for a bit. When the battle begins, remember to have a pet and weapon that best suits you because Livya has over 800k HP. After defeating her, a cutscene with Justice will happen and it reveals that they were friends before she willingly volunteered herself for the Pope's experiments so that Justice wasn't chosen.
Talk to Lord Durok in order to unlock Temar's Room. Be extremely ready as Temar is over 400k HP and his ATK range from 12k to 2.5k each. After the battle, Temar will take a 100-year long nap so go out and talk o Lord Durok again for a reward.
Prerequisite: Get rank S+ in your playthrough (clear all achievements).
Visit Aramute in the Pope's Castle/Aramute's Temple (he is in the furthest room to the back of the castle; Luna doesn't enter the room in this game, but Pieberry did at the end of Witch Spring to revive the Temple Lords). When you talk to him, he will invite Luna to fight him in the Mind Room. Afterwards, the Mind Room will be available on the teleporter.
