I do not know if there are more but some pieces from Archmage set that are suppose to be located in Stone fortress are no longer accessible in Divinity II: The Dragon Knight Saga comparing to Ego Draconis as the landmasses with the chest containing them are missing from the game
the pieces are:
cuirass
belt
necklace
earing
just heads up so you do not waste your time looking for them as I have for last hour
PS: It seems it is still possible to get pieces at random from merchants/chests
