I cannot even beat a lynel with any weapon yet and I have been playing it since launch.
But with in the first 2 hours of getting off that first Cliff I managed to make it to Ganon with hardly anything.
Then my next challenge was to go around the entire edge of the world with nothing but what I could feel me on my way. Did not save up any meals until I got to the snow.
Those are my favorite early challenges.
Besides that I just spend time trying out new things and exploring. Just finally got to my third Divine beast in an area I entirely overlooked...the elephant.
Some day I will finish the actual game.
