The following hero rune (see image) has a 4th stat of "+10% Damage Penetration", which makes it sound like the stat works everywhere (i.e., PvE, PvP, Tower). Consistent with this interpretation, I have other hero runes where the 4th stat specifically says "+10% Damage Penetration in PvP". However, when I look at the stats tab on Drakk's hero card, the rune does not contribute to his Damage Penetration % - suggesting that the rune stat only applies to certain aspects of the game.
So, which is it - everywhere? PvP only? something else?
- If it is for PvP only, the wording should be changed to make that more clear.
