Friendly Bishops II
(Published on 11. October 2021, 21:54 by EspressoMaster)
Normal Sudoku rules apply. Each digit indicates the length of cells diagonally in which it must see a friend. Friends are two of the same digit. One instance of each digit does not have a friend, and two 9s do not have friends. Cage sums indicate the number of friends that the digit in the cage sees, where X equals the digit in the cage. Arrows outside the grid indicate the number of times a digit repeats along the diagonal, and only one digit can repeat along given diagonals. Cells separated by a white dot are consecutive and both digits must have at least one friend. Cells separated by a black dot have a 2:1 ratio and both digits must have at least one friend. Not all black or white dots are given.

Incredible setting, but ridiculously difficult, 5/5 for me, also note that each digit indicates the max length of cells it can see diagonally (eg. the digit 4 can see 1, 2, 3 or 4 away), thanks for sharing!
