Normal sudoku rules apply.
Place 8 different pentominoes (no repeats by reflection or rotation) in the grid such that each is completely enclosed within a box, each touches its neighbours diagonally along a grey line, and each contains digits that sum to 18. No pentominoes touch orthogonally.
The grey lines (links) each show the sum of the two (non-repeating) digits each side of the link. All possible links are shown.
For example, r3c8 is part of the pentomino in box 3, touching r4c9 diagonally, which is part of the pentomino in box 6. The sum of these two digits is 5. Neither r3c9 nor r4c8 can be part of a pentomino.

I'm normally irrationally intimidated by pentomino puzzles, but I really enjoyed this one!

Cool puzzle! Just the short break I needed at work :)

Can pentominoes touch diagonally without a link if the digits on the diagonal connection are the same? That wouldn't be a possible connection, so I'm not sure if that's the intended read.
Edit: solved it without assuming that's fine and it didn't feel awkward to me :)
