All it will do is make alterations to friendship based damge. This applies to ALL Pokemon who evolve through friendship. answered Jan 15, 2013 by Magnegon selected Jan 21, 2013 by grandsox14 devolving reminds me of digimon Please log in or register to add a comment. 0 votes It's happiness drops. That's all. Nothing happens to a Pokemon that needs happiness to evolve when Revival Herb is used.
