Wow I didn't know lgs had that, as far as I knew burnscar and thrummingspark were the only enhancement spellpower items in the game lol... I really need to just look carefully at everything you can do with lgs sometime, and I should probably be farming ings and runes too lol.
"Exceptional" has always stacked with unique values. E.g. exceptional +1 int stacks with +2. Exceptional spell crit 10% stacks with 15%. etc.

WAI since mod 6. Doubt it'll be changed any time soon either.
