[Cancered]

Does anyone know if the defense penetration that Sunder hm skill stage 1 tier 5 provides will do more damage on end game bosses than Sunder stage 2 tier 3? Or does the extra wind damage of sunder stage 2 tier 3 is better than the defense penetration on sunder hm skill stage 1 tier 5? So in conclusion, ~180 extra wind damage or defense penetration will do more damage on end game bosses with my piercing being at 15%?

Defense penetration refers to landing attacks trough block skills, not bypassing the defense stat of an enemy on damage calculation.
