Talk:Magic penetration/@comment-24052974-20141203031853

This may be a stupid and/or redundant question, but is magic damage on hit affected by mr and magic penetration? I assume that it does for Nashor's since that is made specifically for casters, but from items like Wit's End and a stack Feral Flare (Now the Devourer enchantment)? I just thought that it might not since the damage from those items is pretty small when push comes to shove.

And if it does apply, would it be worth it, in others' opinions, to have hybrid pen marks on someone with Devourer, BOTRK, and maybe Wit's End like Ww or Aatrox?
