not sure weather to have put this in bug reporting or here but, when I looked at my Kymons Chosen badge, I seen 100% piercing to lightning conversion, took a look at grenado and…
phys, fire and knockdown on the base skill
fire damage and chance for increased phys damage on high impact
% pierce, fire and crit damage on shattering blast.
In no way can grenado at base take advantage of the kymons badge modifier nor the % pierce on shattering blast.
ok, found a bug then it seems, Grenado doesnt display the pierce damge until you invest in it. If Eis or Jiaco can move the thread then please, cause this belongs in bug reports now
