King Kublai and his archers

Someone asked for more “Kings”… so I made another one.
Here is King Kublai and his archers.
Hello.
Normal sudoku rules apply.
Each box has a King represented by the digit that matches its box number. The digits needed to complete an entropic set and a modular set are rooks.
Entropic sets are low (123), mid (456), high (789).
Modular sets are mod1 (147), mod2 (258), mod0 (369).
(In box 1 the digit 1 is the King and 2, 3, 4 and 7 are rooks because 2 and 3 complete the entropic set and 4 and 7 complete the modular set.)
There is only one King in each row, column and box. Additionally, the nine King positions form a disjoint set, meaning no two Kings may occupy the same relative cell within their boxes (for example, two Kings cannot both be in the top-left cell of their respective boxes).
No King must be in check by a rook within the same box.
Digits on an arrow sum to the digit in the attached circle.
Have fun.
Solution code: Row 9, first 6 digits.

Much simpler than first anticipated. Very interesting ruleset

Smoothest of the kings puzzles for me. Helps that I'm starting to understand the restraint better of course, but this one felt like it had a clearer solve path. Very nice and indeed not too difficult.

Thanks for your comment. I very much agree. I did a lot of case checking on many different arrow shapes so you wouldn't have to. Grts -Jonesy.

I ment to post this as a 2 star puzzle. It may end up as a 3 star but it's actually easier than it looks at first. The placement of the arrows should keep case checking to a minimum. Hope you enjoy!
