Super effective charged attacks are regular charged attacks that target an opponents weaknesses in Pokemon Go. These attacks can deal increased or critical damage due to the differences between the attacking Pokemon and the Pokemon receiving the damage. To perform a super effective charged attack, you need to ensure that the Pokemon you have in battle is of a type that the Pokemon you are facing is weak to, and the move you are performing with that Pokemon is of a type that is super effective against the opponent.
To use a charged attack, you need to collect enough energy from using fast attacks in a battle. Once the attack button slowly fills up, you can use a charged attack. It can be difficult to land a super effective charged attack as you need to have a Pokemon on your team that is super effective against your opponent, and you wont always have one.
Knowing the different Pokemon types and their specific weaknesses or strengths can help you identify what would be a super effective charged attack. For example, if you have a Water-type Pokemon that uses a Water-type attack against a Fire-type opponent, it will deal super effective damage as Fire-types are vulnerable to Water-type attacks.
In summary, super effective charged attacks are regular charged attacks that target an opponents weaknesses in Pokemon Go. To perform a super effective charged attack, you need to ensure that the Pokemon you have in battle is of a type that the Pokemon you are facing is weak to, and the move you are performing with that Pokemon is of a type that is super effective against the opponent.
