I hope the Forgotten Land DLC gives us some juicy lore/hax.
Yeah.
I mean, I saw the crystal do stuff like Platform Creation, Earth/Crystal Manipulation, I think it parted some waves then turned it to crystal, so Water Manipulation & Transmutation.... There's also the ferris wheel, so energy/light/electricity manipulation, depending on how you interpret it, assuming that's not just distant light of colourful very shiny crystals or something, lol. (No offense meant.)
There was also that reddish pink, fire-like energy we saw burning when the crystal heart was falling.
Enemies with it also seem more aggressive, & the Miniboss Frosty with it is named Crystal Wild Frosty. IDK if it's give the affected Rage Power/Berserk mode. They probably also have new moves, but I don't know the base game or most of it very well.
So that's probably Morality/Empathic Manipulation, technically Mind Manipulation, too. Maybe Animal Manipulation, given what it affects?
Since it powers up the enemies, it may also be able to qualify for Empowerment, &/or Blessed &/or Statistics Manipulation, maybe.
It also seems like some areas of the ground have purple stuff that may resemble acid. IDK if it damages on contact, & didn't see any lore about that, nor do I recall if they ever stepped on it/took damage.
May qualify for Acid Manipulation, Darkness Manipulation (Funnily enough, it'll probably also end up getting Light Manipulation because crystal shiny, lol.) , &/or Corruption?
That said, I doubt that that's much wild, since the Kirby series already has a lot.
You have to get pretty crazy to be impressive by the Kirby franchise's Powers & Abilities standards, I'm sure.
Hopefully that's helpful &/or interesting, or at least appreciable.
