@Faefana It won't increase when not in use, but for increasing effectiveness and whatnot simply do what they do for tk in fiction and try really hard idk. The more you push it to be better the better it will become even if it's something small like trying to interact with something 1cm farther away each day, progress not perfection. 😇 You can do the same thing over and over again and continuously improve but have to increase the magnitude/scale you're working on, so you don't need to worry about making some new training method because one isn't working anymore. We could say if it does stop working that means you've hit the cap for that aspect of the power and need to strength the rest of it to that same level before it evolves into its next power. E.g. For Warping you can now use it on something on the other side of a planet (planetary scale reach) but can't actually move the mass of a planet, so you have to train moving different weights until you get there. I could just give an Independent Growing Booster that only tracks and promotes growth but that would be too easy.
As for DI ig it could but looks like it will end up in the same place as Warping through different means at least looking at the Ultimate Applications.
tldr: Fully just put in some effort and the power will grow. Train it like you would a muscle or maybe how you would the human body, might be better idk.
