I'm currently playing a Duergar Barbarian who I'm playing as a grappler, great fun, but neither me or the DM are entirely sure how the Duergar's sunlight sensitivity affects a special melee attack. It reads as follows.
Sunlight Sensitivity: You have disadvantage on attack rolls and on Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct sunlight
I've seen similar situations ruled differently by different DMs. I suppose I'm asking is an attack roll strictly against AC, or is a contested roll from a special melee attack also defined as an attack roll?
