Rules
• Normal Sudoku rules apply. Place the digits 1-9 in each row, column and box without repetition.
• Knightmare: Cells that are a Knight's move apart (in chess) may not sum to 5 or 15.
• Arrow: Digits on an arrow must sum to the digit placed in that arrow's circle. Digits may repeat on an arrow if allowed by other rules.

I made that way harder than it should've been. Very well made!

Beautiful use of the knightmare constraint, brilliant setting, challenging but fair!
