To name a few:

Applications of friction manipulation

Variations of adhesion

Electrical wall crawling

Technique of vacuum manipulation/generation

Supernatural Balance

You could attract yourself to the object your trying to climb

Perosnal gravity

@DOPOP Can you explain why Supernatural Balance is here? Do you mean user's balance is so great that they stand on a wall and don't fall because they balance on vertical surfaces?

Their balance is so enhanced they can move freely on surfaces with only the slightest imperfections allowing them to scale walls, ceilings and essentially move freely on most surfaces. So as long as the surface has even a minuscule imperfection the user can move across it and nothing can be truly flat

@DOPOP Ah, so you mean if any surface isn't completely smooth but bold in some way or another, user could simply balance on them and not fall? This is actually a great feat, honestly, I didn't even think about it. But what is surface is completely smooth or user stands on a horizontal wall upside down? It wouldn't help then?

I’m not sure I guess if they could balance regularly they could also grip onto the surface with hands and feet depending on how strong the user is

@DOPOP You are indeed sneaky! Wouldn't that tiny pieces of surface user balances on simply break under user's mass?

Maybe not if balance correctly and distribute their weight proportionally

And it depends on the surface and how quickly they move

@DOPOP I see. Although I chose Telekinetic Attraction in case for character but I think Supernatural Balance would be an emergent tool if Telekinesis is not available. Thank You for all Your answers! I appreciate it, You helped me a lot!
