As-One-Spectrier

As One (Spectrier) is a special ability exclusive to the fusion of Calyrex and Spectrier in the Pokémon series. This fusion is formed through the use of the "Reins of Unity" item, transforming into the formidable form known as Shadow Rider Calyrex.

The key effects of the As One (Spectrier) ability encompass:

1. Combination of Abilities: As One (Spectrier) cleverly combines the abilities of both Calyrex and Spectrier. More precisely, it amalgamates Calyrex's Unnerve ability with Spectrier's Grim Neigh ability.

2. Unnerve Effect: This component of the ability bars opposing Pokémon from consuming their held Berries during battle. This is capable of disrupting strategies that are dependent upon Berry consumption for recovery or status remedy.

3. Grim Neigh Effect: Each time Shadow Rider Calyrex topples an opponent, its Special Attack stat is elevated by one stage. This effect further enhances the potency of Shadow Rider Calyrex's subsequent attacks.
