Nonoknights II

Rules:
Normal Sudoku rules apply. Place the digits 1-9 once in every row, column and 3x3 box.
Nonogram: The numbers outside the grid define a nonogram. Shade the cells in the grid so that the pattern of shaded cells matches the numbers given for each row and column. See the example of a solved nonogram below. A digit in a shaded cell must see the same digit a king’s move away at least once. All shaded cells are given; that is, a negative constraint applies.
Anti-Knight: Cells separated by a knight’s move in chess cannot contain the same digit.
Kropki dots: Cells separated by a black dot must have a 1:2 ratio. Not all possible dots are necessarily given.
Magic square: Somewhere in the grid lies a 3×3 magic square that contains all digits from 1 to 9 exactly once, and in which every row, column, and diagonal adds to the same total. It's up to the solver to determine the location of the magic square. (The magic square can occupy cells from different boxes.)

That was excellent! I had to switch around my strategies several times based on whether I was coloring a nonogram, coloring a sudoku, finding a magic square, or solving the thing entirely!

Wow, just wow. Great colouring puzzle. Took me a while to get a grasp of what we were supposed to do but as soon as I saw it, I could get a move on.
A very slow move indeed, even knowing what's to do, it took me hours over the entire evening to colour everything in and work it all out. Having the colouring, the nonogram, the magic box, it just makes it so versatile and fun. This is one of those 100% puzzles.

Very smooth solving path from start to finish, but took me a long time to follow that path. Never really got stuck, I found the correct path from the start and followed the path I expected until the finish. It was just a lot to figure out.
