I want to leave it very clear... touch even the air around Nei, and I guarantee... I don't care if you're a god or whatever shit you call yourself... you will pay in a way you could even imagine.
I am starting to see a pattern in the abilities, kinda late I admit, but with Prachi's ability being a "materialization" ability with "self-enhancement" effects, a "map" of the categories abilities can fall kinda popped in my mind.
The ones that come to mind are... "spatial construction" and "spatial manipulation", "object materialization", "transmuting" and "transforming" matter, "self augmentation", "energy manipulation and generation" and a few more that I can't quite categorize.
And it is important to account for the "themes" that come with each "obsession" of the users which gives them some restriction, condition, or secondary mechanics.
