I have a Golurk with the Ability Iron Fist
It also has Power-up punch
Will Iron fist upgrade Power-up punchs power?
If so how much does it upgrade
BTW Power-up punch has 40 base power and raises the attack after it is used
Yes Iron Fists increases the Power of Power-Up Punch by 20%.
So with the Iron Fist Ability the Power of Power-Up Punch will be increased from 40 Base Power to 48 Base Power.
(40 x 1.2 = 48)
It will also raise the users Attack by 1 Stage.
Yes, it ups the power of Power Up Punch
Hope I helped!!
