After damage is dealt, Ancientpower has a 10% chance of increasing all of the using pokemon's stats (Attack, Defense, Speed, Special Attack, Special Defense) by 1 step-level on the Stat growth scale. If one or more stats have already reached the 6-step growth limit before this boost, the previously affected stat(s) will not be increased while the others get the bonus.
Ancientpower is affected by Brightpowder when the opposing pokémon is equipped with it.
