Idea
1) ability to see the branching potential of a quirk/power and also figure out how to achieve them
For example the generic fire ability, the power will be able to see the different ways that it can be used or improved e.g. increases temperature, turn body into fire like logia, change what types of things the fire uses as fuel instead of air it will instead burn hair, sticky fire, cold fire, turn the initial fire ability into something related to fire ( magma, temperature, burn weakness)
This ability can start out weak with the user not knowing how to use it or what it does, but slowly getting the feeling when seeing other quirks and others saying they can't do this certain action beacouse their quirk doesn't work that way, then telling them they actually could.
The user chould sell their services for money or beacouse a teacher or maybe develop another persons quirk to be able to benefit then user
If anyone wants to use my, idea you but mention my Webnovel( this one )
P.s im trying to think of a cool name for it…. Something like "unrealised potential" or "undiscovered need" something like that if you have ideas post them in the comments
