Runic Power

Runic Power appears as a blue bar

Runic power is the secondary resource used by death knights.

Runic power builds up as the death knight use their abilities, displayed as an empty bar that fills up with a light sky blue color under the death knight's health bar. Generally, offensive rune abilities generate 10 runic power per rune required to use that ability. Additionally, [Empower Rune Weapon] generates runic power without costing runes. Death knights can hold a maximum 100 runic power. As with rage, runic power gradually diminishes when not in combat.
