Making an emission shader which does NOT cast light So i tried gooogling and asking around in discord servers but no one is really helping nor understanding what I need.

To sum it up, I need an object to LOOK like the sun in 3d space, aka it needs to be very bright. "just put an emission shader on it duh!" well there's a problem! I have cell shading and the size of the object depends on how smooth the shadow is! So if I have one light source which is huge, casting a very huge smooth shading all over my cell shaded objects, it just looks weird.

So - a fake glowing object. I just need an object that looks like its glowing but does not cast a shadow. That's all.
That's easily solved. Find a tab in the emitter's Object Properties called "Cycles Settings".

There's a bunch of things there that you can tell Cycles not to do when it munches through the object. The interesting checkbox in this case is : Diffuse. That tells cycles: ignore diffuse reflection rays for this object.
