Larian Studios Forums Divinity II The Dragon Knight Saga / Flames of Vengeance (English) Divinity II - The Dragon Knight Saga Just need some answer before buying

I would guess the downloadable armour sets for the PC version of D2:ED might possibly work with FoV, but will not for the PC or Xbox versions of DKS. I don't recall if there was ever an official comment on that either way.

With either FoV on PC or DKS on Xbox/PC you can start a new level 35 character at the beginning of the add-on content, if you want to get to the add-on before (or rather than) starting over with a new character.
