Shadow Sneak deals damage and has a priority of +1.
Moves with a higher priority always go first, regardless of a Pokémon's speed. If two moves with the same priority are used, the faster Pokémon goes first as usual.
When a Pokémon is holding Ghostium Z and uses its Z-Power, Shadow Sneak turns into Never-Ending Nightmare and has base power 100.
