Stealth kills

Stealth Kills were a game mechanic featured in Blood Omen 2 based on the Mist Dark Gift.

Kain was given his first lesson on Stealth Kills by Umah's tutorial in Chapter 1: The Slums, when he was first introduced to the Mist Dark Gift. As with the usage of Mist in Blood Omen 2, Kain could use floor-hugging vapour to hide his presence and enable him to sneak up on enemies from behind; when autofaced, a skull icon would appear above the target's head, and Kain would perform a quick (and often gory) one hit kill Certain enemies, notably the Sarafan Glyph 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

Types of Stealth Kill
Stealth Kills varied depending upon the weapon that Kain was holding and each 'weapon' had two Stealth Kills (one using just the "action button", the other combining the "action button" with the "direction buttons").
