Nox Omen

I'm guessing the new character would be Ava's sister

I ended up forgeting about this but Dred just released a video showing the difference. Alexandra actually has somewhat intresting dialog if Karen is dead.

Level up after learning Psyshield Bash and that's it

Umbreon is bulky and can Toxic stall (eevee obtainable during the lost souls quest) Honchkrow with Moxie and Tailwind (murkrow found in Darchlight woods at night) Malamar with Contrary and Superpower (Inkay obtainable during Bo's quest in Yui's Ranch) Spiritomb damage becomes somewhat significant after you get it's crest and is a good staller as well (Goldenwood cave? and the crest is in Castle Zygara) Incineroar with Intimidate is bulky and deals a good amout of damage (East Gearen post strenght) I'd say this are somewhat viable choices (some better than others). Some Pokemons are only obtainable quite late in the game but you can always swap Pokemons of your team for new, better, options.

Run the updater program in your game folder to update to the latest version of the game and the problem gets solved

I started playing at V9 as well and I have memory of starting playing the game about 6 years ago but V9 could have been out for some time already. EDIT: Also if you search Pokemon Rejuvenation V9 most posts and videos are from June and July of 2017. And from what I'm picking up V8 came out in the middle of 2016 and V10 in early 2018.

In that case yeah, you need to go to the Castle Zygara which is at the end of the Zorrialyn Labyrinth. Can't remeber if there is actually a part 4 to the Hidden library quest but Karen only appears in Alamissa Urben and gets taken to the inn if you did the 3 quests before so it's basicly a continuation.

I have played through the Paragon route but I'm still playing through the Renegade route (Got to Grand dream city today) so I don't know the intricacies about the former yet. But I heard that keeping Karina alive might be useful and I heard that

Go to Amber's chilling spot where you fight Jenner in the terajuma ark, head to the stairs bellow. After that get through the slope maze and go up the stairs in the middle of it and you're where he is supposed to be.

To the lowest floor of Zorrialyn Labyrinth maybe? Did she give you the Hidden Library part 4 quest? As for the time limit part, can't say for sure for this version but I think there is no time limit.

Darchlight cave has been revamped and...

You're welcome. It's kinda easy to miss if you don't know what you are looking for since most wouldn't even think to look for it in Viennas Hill.

You are always by default in the paragon route. In order to even being able to choose the renegade route you need to do certain things like: But once you actually reach a certain point in the game, if you have met the requirements to choose the renegade route the game will leave it somewhat clear that you are choosing it and that you can choose to simply continue the paragon route even after all you did.

The girl tells you to put a mail in a mailbox in Viennas Hill
