Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems Lump The Enlightened - permanent intelligence of 19

If I had to guess there are two things at play here:

1) Equipment not working properly on NPCs in some way, so they gave him the stat manually
2) When they nerfed the headband from 19 to 17, they forgot to nerf the NPC stats too

But I don't really see how his intelligence when dead matters to the game.
