You gave examples for the creation trio, but I was wondering what it would be like on that rare occasion a pillar attunes to Arceus?
What you mean power wise? That’s pretty dependant on what your interpretation of Arceus power as a higher being is!To me personally Arceus represents Order, Stability, And Creation.So I suppose if we use that as the standard.Arceus attuned Pillars would probably be able to bring order to chaos, stop reality from falling apart (think; nullifying Dialga and Palkias effects in the darkrai movie for an example), or maybe in some small part be able to create things? Itd be a lot weaker than Arceus itself (and mew for that last example)But theyre basically almost like vessels for the legendaries original power.I hope that helps answer your question!
