Deconstructed Treasure Hunt

Normal Sudoku rules apply. ARROWS: Numbers on arrows sum to the number in that arrow's circle. Arrows are consecutive cells on the grid, connected either orthogonally or diagonally. Numbers may repeat on arrows, if other rules allow. There are 8 VIRTUAL arrows not shown in the grid, but have the 9's shown for their circles. The arrows TO the treasure have only 1s, 2s and 3s on them and have blue shaded tips. Numbers in the top left corner of the arrows' circles are the length of the arrow, if given. Once you have found the treasure, the arrows that show your escape route have only 4s and 5s on them and have pink shaded tips. Numbers with an X between them sum to 10. Numbers with a V between them sum to 5. Not all X and V are given. 8s are never orthogonally adjacent to 9's.
