The rune system

Instead of mana, energy, or rage, DKs will have runes. This image is from the 2007 BlizzCon presentation on the DK class. The runes come in three different schools: blood, frost, and unholy, which match the DK's spell schools and talent trees. Activating an ability causes runes to deactivate; the number of runes deactivated depends on the spell's power. The runes regenerate after a cooldown, similar to Rogues' energy (though probably slower).
