Do penetration boosters give their bonus for natural attacks that allow resistance? For example, if I give an Aboleth an eye of the void, would he get +2 on his enslave mind attack?
Not sure about items. Most natural abilities do not get a penetration boost AFAIK. Not sure about units that auto-cast spells at the beginning of a battle either.
this is an interesting question. i have been messing around with ethereal crossbow(infinite damage). MR negates this weapon, and i was wondering if boosting the hero with magic focus, eye of focus etc would help...
