to put it into a way its understandable, lets say he starts off with making a ripple with a step on the ground simple and plain, but progressively in the story it evovles and mutates into something like the character having the abilty to manipulate time and cause ripples and the such,
Basically forced OP on supossedly simple ability. Any technique that can shake the ground can also produce similar result.
And the strongest kind of ripple on ground is called Earthquake. You can make the user move the tectonic plate if you want it that way, destroying the ground of several kingdom and causing tsunami waves. It's 100% kill rate due to the effects of the move.
But, Time ripple usually only affect those protagonist or any character who get transmigrated into novel or such (or at least some future revelation), Because you need to know the future if you want to affect time flow.
Still tho, dimensional ripple that cause bending of reality fabric sounds like a supposedly complicated topic that I can't really imagine MC have it harder than influencing timeline.
Well, that all another food of thought from me.
