I've been looking at the Artificer character sheet in my campaign. They're level 18 and somehow they appear to have Expertise on all INT-based skills. I've looked through all features and items to see where this is coming from. They have Expertise in Arcana from the Skill Expert feat. Otherwise, I have no idea where this is coming from - I've checked to see if they've customised any to give them Expertise but they haven't.

Any thoughts?
Resolved, it was from attuning to the Book of Vile Darkness
