This one is my fourth Vampires puzzle. I made it to join one setting prompt by isajo4002, and I felt it was time for a proper invasion of vampires this time. So welcome, 'cause a wild fierce battle will start tonight between vampires and werewolves on this mountain.

You can think at this puzzle as a sequel of Little thirsty vampires and Vampires in town.

Rules

Fill the grid with the numbers from 1 to 9 so that in each row, column, and 3x3 block each digit occurs exactly once.

In addition, the grey cells in the grid portrait a mountain. Its peak is in a cell with the highest value in the central box. The mountain consists of all cells which can be reached from the peak by repeatedly moving from a cell to an orthogonally adjacent cell containing a smaller digit.

The pink circles in the grid are vampires: they take exactly one sip of blood from an orthogonally adjacent cell. For mountain's purposes, vampire cells have value increased by exactly one and the taken cells have value decreased by exactly one. Vampires cannot bite other vampires. Two vampires can't bite the same cell.

The brown squares in the grid are werewolves: they are watching the mountain in search of vampires. Digits in a werewolf cell are the sum of the values of all the vampires in its row and column. Vampires cannot bite werewolves.

Examples of how mountain rules work can be found in Nylimb LMD page, who is the creator of the rule, for what I know.

Have fun solving and please leave a comment after your solve!
