Hi, i just have the idea of a new use of this buff. What about if the penetration can hit enemies with invencibility. I mean, you hit an enemy with invencibility and nothings happens, but i you have some tipe of penetration, you deal some damage, like if the enemy doesnt have invencibility and you dont have penetration.

Sorry for the gramatic, english isnt my native languaje.
Thankssss
