It doesn't change anything (both your touch attack and my attack roll were plenty high enough without the proper modifiers), but McToughy was in N10 for the AoO, and wouldn't have gotten the +1 for higher ground and may have had cover against the spittle attack. But as I said, the modifiers don't change the outcome; I'm just keeping us on the same page.
