v141 Cygnus Awakening - Bugs and Glitches

I have an issue with the Thunder Breaker skill Ironclad, I use the buff which states 5% damage and -10% damage absorption. It has no effect on my range at all, is this intended? Is the damage stacked ontop of all the attacks or is it passive? Does it just not show in the range window..?

Oh, someone else already mentioned this. ~_~
