Logic Masters Deutschland e.V.

I found this URL carved into the side of a tree in the forest last night. Is anyone brave enough to try it?

Rules:

Fill in the grid with the digits 1 to 9 once each in each row, column and box.

Adjacent digits along the blood red runes must differ by at least 6.

The dotted lines indicate zones of power. Digits may not repeat in a zone and the value of the zone is the sum of its digits.

Diagonal arrows indicate ley lines. The value of a ley line is the product of the values of all zones of power that intersect that ley line. For instance, the value of the ley line starting with r1c4 is the product of the 2 cell zone starting at r1c4, the 2 cell zone starting at r1c3, and the 8 cell zone starting at r4c1.

Every ley line must achieve the same value for a successful ritual, and after discovering this value it must be filled in the designated red box at the bottom.

Thanks to marty_sears for helping me edit and pushing me to set this final version, and the CtC discord for testing. All feedback (positive or critical) appreciated!
