Rage

Rage is a concept seen in Blood Omen 2, Kain gained Rage in Combat through blocking enemy attacks. A certain level of Rage was required to utilise the Dark Gifts Fury, Berserk and Immolate.

Rage is seen throughout Blood Omen 2 as the attribute is represented by a 'Rage Meter', above the weapon icon on the HUD (Head's-Up Display) used in-game. The bar would fill up a small amount for every enemy attack that Kain blocked whilst in Combat mode.

When the Rage Bar reached a certain level (about a third for Fury, two thirds for Berserk and completely filled for Immolate), the bar and Kain would glow red indicating a Combat Dark Gift could be used and allowing Kain to use the respective Dark Gift.

Kain was first taught (indirectly) of Rage in Chapter 1:The Slums, in Umah's tutorial, where Umah taught Kain about the usage of Fury and blocking.
