Rules:
Regular sudoku rules:
Place the digits 1-9 in every row, column, and box
Killer Cages:
Digits in a cage cannot repeat. If a number is given in the upper left corner of the cage, then the digits in the cage must sum to that number.
Anti-Knight:
Cells that are a knight's move (in chess) apart must not contain the same digit.
Oil and Water:
Each cage is either full of "oil" (even digits), full of "water" (odd digits), or a mix of both. In cases where cells of a cage are connected to each other horizontally, those cells must only contain one type (oil or water). If two cells are a part of the same cage and in the same row, but they are not connected horizontally (r5c6 and r5c8 for example), then they can be different types. Oil floats on water, so even digits will always be in rows above odd digits in mixed cages.
Anti-Knight:
Fog will revealed along a set path as digits are placed.
Lösungscode: Even digits in row 7 read left to right.

Very nice puzzle! Seemed impossible to me (I usually do up to 2*) but after using some colors and some letters I could break in! Thank you!
Merdock: Thank you for playing the puzzle and congratulations for completing it. I know what it's like to face a daunting puzzle and the joy when you surmount it, so I'm incredibly happy for you for solving it.

again lots of fun,
it's been a bit since I last played an oil&water puzzle, so this too nearly an hour to solve.
didn't understand the fog at first, but the moment the first cleared it was the classic Homer Simpson Moment ;-)
very lovely puzzle, very nicely set.
Again, got a bit rusty, so the initial break in for the colouring almost escaped me... but I loosened up ... I think.
thanks for setting & sharing
Merdock: Thank you so much for the compliment. I think a shout-out to Blobz is necessary as I have thoroughly enjoyed their Oil and Water puzzles and inspired me to have a go at them. I've been exploring different styles, and this was one of the more enjoyable ones to create.

Updated puzzle to factor in deduction that I think Gallium_odoratum was hinting at. Increased difficulty to 3 stars. Updated tag list

Fun colouring puzzle. Definetely a 3* in my opinion. Also the 1st fog reveal was too early, there was still one possible deduction (= entering a digit) left. Still solid puzzle with good flow, thank you for setting!
Merdock: Nice Catch, I didn't see that additional deduction. Thank you for the comment.
