The ability made a return in Blood Omen 2, where it was one of Kain's few abilities to survive his brush with death and was his first 'Dark Gift' from that game. Mist was used primarily in Blood Omen 2 to aid stealth, enabling him to effectively disappear in low level fog and whilst in this form, he could evade or perform one hit 'stealth kills ' upon enemies. Certain enemies, notably the SarafanGlyph guards and Glyph knights had special armour that could detect a vampire nearby - they weren't able to see Kain (unless he moved directly in front of them), but it did make stealth kills much harder to perform upon them, if not impossible[Blood Omen 2].
Legacy of Kain: Defiance again showcased the Mist form, this time much more developed. Along with allowing Kain to pass through grates and the like (Kain's Material Realm answer to Raziel 's 'Phase Through Gates ' ability), Kain now used his mist form in combat allowing him to effectively dodge enemy attack without having to move far (Raziel would have to rely on greater speed to effectively dodge.)[Defiance]
Presumably Kain still possessed Mist form in his appearances in Soul Reaver and Soul Reaver 2, although it was not shown.
The mist form was not originally to have been in Blood Omen 2, which instead would have featured a 'Stealth ' Dark Gift which enabled stealth kills anywhere, it is likely this was changed to the classic Mist ability for issues of balance. Within the game, a 'stealthy' Dark Gift such as Mist may have been used to deliver a message to the Tapster in Chapter 2:the Smuggler's Den.
Across the series, Mist is one of the more consistently presented abilities, with the same title and similar applications given to the mist form in all games in which it appears (in contrast to several other abilities that despite being similar to existing abilities, are given different titles or have to be re-acquired)[Blood Omen][Blood Omen 2][Defiance].
