List of second Charged Attack cost

After the launch of Trainer Battle, Pokémon with more than one Charged Attack can learn an extra attack by paying Stardust and candies. Both attacks are usable in Gym, Raid, Trainer Battle and against Team GO Rocket. Like Buddy Pokémon mechanic, the costs for different Pokémon are divided into four groups. For most of the cases:


 * 1 km Buddy distance = 10,000 Stardusts and 25 candies,
 * 3 km Buddy distance = 50,000 Stardusts and 50 candies,
 * 5 km Buddy distance = 75,000 Stardusts and 75 candies,
 * 20 km Buddy distance = 100,000 Stardusts and 100 candies,

Starter Pokémon (and their evolution) and Baby Pokémon are exceptions. They all cost 10,000 Stardusts and 25 candies.

When a Pokémon with an unlocked second Charged Attack is evolved, the evolved form will also have it unlocked, although it could be a different Changed Attack.
