Echoed Voice is a sound-based, offensive Normal-type move.
Echoed Voice deals damage.
Its base power increases by 40 each consecutive turn it is used, but reaches a maximum power at 200. However, the power will not increase during a round and will only increase once per round (regardless of how many Pokémon used it).
The base power of Echoed Voice doesn't reset upon reaching its maximum. When failing, the base power will still increase as long as the move is executed, such as when it misses or is prevented by Protect.
