Going by its description, it says it ignores Defense, but, it only adds a flat number to your damage still equal to the amount of Defense it claims to reduce, and after some tests done against an unarmored then lightly armored target, I think it's just ignoring an amount of Armor equal to the Defense it says its ignoring (10 at max rank).

So, either it needs to be updated to say 'ignores x Armor' or changed to actually ignore that amount of DEF. I think Armor would be easier personally. And that's what it already seems to do.
