The foe faints if the user does.
Destiny Bond is a Ghost-type status move that, when used, causes the opponent to faint if they knock out the user with a direct attack on their next turn. This move adds a strategic layer to battles, as it can deter opponents from attacking or force them to consider alternative strategies. In Polished Crystal, Destiny Bond can be learned by various Ghost-type Pokémon, providing them with a unique tool to potentially take down an opponent along with them in battle.
