In BG3 you can right click examine any item or character. This reveals their type, their special attributes and other information that makes disguises basically useless against the player. It also reveals their HP and resistances, so unlike actual D&D where you would need knowledge checks or special skills you just have perfect information. You can even scroll the map to see ambushes hidden in other rooms before you go in.
You can detect the Hag and Orin quite easily in their disguises, and just immediately attack them if you want without doing the in game work to “reveal” the plot. Huh why does this random blacksmith have legendary actions? Why is this random innkeeper a fey?
Also for some reason by default it displays failed perception and survival rolls so you know you missed something and can just go back and hover over everything or dig around in the ground when you fail a check.
Also was anyone actually buying Astarion’s “I’m not a vampire” shtick when he has fangs and his mouth is dripping with blood in the cover artwork?
