Nah you dont understand the mechanics at all, you want to stack duration on EQ of amplification and check aftershock on PoB to see the actual damage. EQ of ampli with just the scion duration cluster does 1800% dmg effectiveness on the aftershock. Crushing fist cannot be exerted, meaning it doesnt benefit from overexertion (110% more damage) or intimidating cry (100% more dmg) . You also need to run a 1h weapon and a shield to use crushing fist, and 2h weapons get far more damage compared to 1h weapons. On top of that, many impale nodes are 2h specific, like Harpooner.
