Light of Ruin possesses significant KO potential, allowing Mega Floette to eliminate many Pokémon, even those not inherently weak to Fairy-type attacks. However, this power comes with considerable recoil damage and a 10% miss chance. The strategic value lies in recognizing when these risks are worth taking. The optimal outcome often involves using Light of Ruin to secure a knockout on a key, bulky opposing Pokémon, effectively trading Floette's significant HP for two opposing Pokémon, or one high-value target.
