I ran into this in my current campaign, in which I am the DM. My players were fighting a half-orc and one of them decided to use his Inspiration point to gain advantage on an attack roll. At the time, he was poisoned so I assumed that the advantage and disadvantage would cancel out. He told me that Inspiration gave automatic advantage to any roll, disregarding any disadvantage. I don't know which is correct, RAW or RAI.
Can someone please help me clear this up? Thanks!!
