Puzzle: CtC

Rules:

Normal Sudoku rules apply.

Digits in cells separated by a black dot are in a 1:2 ratio. Not all dots are necessarily given.

Digits along a purple Renban line must form a consecutive set of non repeating digits in any order.

Digits in cells separated by an X sum to 10. Not all X are necessarily given.

No adjacent digits may be consecutive.

Cells in the same relative position in their boxes cannot contain the same digit.

Kropki Cross: The digits in the red cells are in a Kropki relation with the digit in the blue cell. This means that they are either consecutive or in a 1:2 ratio with the digit in R5C5.
