TeneSicarius

I don't know how many know this, I haven't seen it on any of the walkthroughs that usually talk about hidden items, but there's a revival herb in the Xen base in the volcano. In the top right room, bottom left corner, on a cushion. What makes this really weird is that this area is limited-time, and you don't have the itemfinder yet, so you'd have to manually check all the tiles to find it. I don't know if there's anything else like this. It's been there for a few versions now; I've found it in v12 and v13.

Weird necro, but I guess I can answer it. Use reverse candies to level it down, then it can regain it's level up moves. So, use 10 reverse candies.

No I said them getting shinies after Kieran messes with their mind; I never mentioned ryland or ancient times or Leisel or anything even close to that. One shiny in your life isn't weird in-universe, Melia's full shiny team is just shy of being outright stated to be as a result of Arceus's Light, and unobtainable for any normal person (Our character's shiny rate might also be highly unusual), and Adam is only non-generic NPC aside from Melia to have more than one shiny across all difficulties (Where Love Lies shows that Keta's Ninetails was a gift from Tesla, and I think his Lucario might've been something from his father; talking with it requires a close bond, and he didn't develop that until Chapter 3 in that game, yet it was evolved at Chapter 1). Young and new trainers basically never have a shiny pokemon (Ren, Venam, Aelita, Amber), the weaker gym leaders (1-8) have no shinies (except Keta but unlike the rest he's not a new gym leader), while every gym leader that isn't a replacement has a shiny. Florin's weird because it's only on one version, and that version isn't the default one, and the Intense Major Battles doesn't say that any pokemon are supposed to be shiny aside from Sceptile. Kieran not having shinies might imply a different reason for Adam having 2, and also imply that Kieran doesn't have any Light of Arceus. Shinies are usually someone's ace (aka naturally stronger than the rest of their team), the dialogue with Vitus implied that being shiny is a result of having Arceus's Light. Plus from Rift Aelita we know that rifts are based on inner power that pokemon naturally have more of (and her rift is a Regirock, and Vivian had the power to create / summon Regirock on the spot), and we know of two rifts being made from shiny pokemon (gardevoir and garbodor), but it's hard to tell if they're canonically stronger than normal rifts or if the other rifts are weak cuz they're early game. Vivian having none, and Aelita not having any shinies on either of her two teams might imply that whatever Vivian had about listening to the world has nothing to do with Arceus (or gaining shinies after awaking the power confirming it). The 3rd thing is that shinies might've only started appearing after Storm 7; while the game doesn't change your shiny odds in the past (and Melia can find shinies in the destroyed world), no one in the past had any shinies on their teams; the Regis might be shiny cuz I remember Angie piercing herself with a red crystal to summon Regice and shiny Regice is blood red, and Vivian never battled with Regirock, and the golems are called "gifts from Arceus". Gardevoir's "Past Reflections" showed her as a shiny ralts, but Vitus messed with her mind a bunch that it could go either way. We'd need Mr. Luck to talk about his ralts to know if it was actually shiny, but if it was, and that Vitus talked about it's true power in that scene because it was shiny, and him "taking back his power", I kinda think he's the first human that despises pokemon for having more of Arceus's power, since the Narcissa sidequest shows that he never ages and takes on new identities all the time. It's hard to actually gain any useful information from any of this; at best it'll just help point to important things in the future. Edit: Thinking about it more, for normal people, it's probably more likely that experienced trainers have a shiny, and people who've explored a bunch have a shiny. The Puppetmasters and Souta have essentially been raised in captivity, no shiny. Ryland is experienced but never left the badlands, 1 shiny. Adam is experienced and spent most of his life exploring, 2 shinies. Ren / Aelita are new trainers only just starting to explore, Venam / Saki / Amber / Crawli / Valarie are young / new leaders that mostly stick to their own towns, no shiny.

Prankster Tailwind and Misty Terrain don't target though.

Something I noticed on my 3rd replay of Rejuvenation was that Erick is the badge that gives Strength, even though beating Flora / Florin gives you the actual HM. I wanted Prankster Whimsicott for the Rift Gardevoir fight, so I was thinking about how I could get it without boarding the train to GDC. I tried using Golden Gauntlets, but they had the Use button disabled. So I went to bulbapedia to see if anything learned Strength without a HM, and saw the only Gen 7 to do so was Machamp. So I used a Link Heart on Machoke, since Machamp learns Strength on evolution, and it worked. I got all the Strength blocked things like Reaper Cloth, Gastly, Feebas, and the Caratos Mountain vendor. There's still only 2 blast powder this early, so you have to choose between getting Abra, Prism Scale, or the Caratos Mountain vendor. I left the prism scale, obviously, but in a future playthrough I could get a Milotic without having to wait until right before Adam.

I was thinking that, Adam had more than one shiny in all versions, and 4 shinies in Intense when his team changes to Normal when you control him, which is very unusual. If his team got changed around due to Kieran, and if next chapter we can battle Valarie and she also has a changed team with new shiny pokemon, that might point to then also having some of the same powers as Vitus.

Something I realized when replaying the game was the encounter with the Rift Gardevoir: When Vitus takes back "his power" from Gardevoir, it loses it's shiny form. And in the doomed timeline, Kenneth said that there'd been no new shiny pokemon since the doomsday event Shiny Pokemon might be plot-relevant a few chapters from now; I've been paying more attention to which pokemon on each team is shiny, and which gym leaders carry shiny pokemon.
