After damage is dealt, the pokemon that used Psycho Boost will have their Special Attack reduced by 2 steps on the Stat growth scale.
The stat reduction that occurs when Psycho Boost hits can not be prevented by any means. This stat reduction can not bring the pokemon's Special Attack lower than 6 steps below normal due to the 6 step limit.
Psycho Boost receives the flinching bonus when King's Rock is attached to the using pokémon.
Psycho Boost is affected by Brightpowder when the opposing pokémon is equipped with it.
