WoW - Wrath of the Lich King - Hands On @ Gamespot

Ricardo Torres hands-on.

While we weren't able to play the new class, we were treated to a brief demo showcasing the Knight's finer aspects. The standout elements of the Knight are its rune powered spell system. A series of six rune slots will rest beneath a Death Knight's life bar and hold any combination of the three rune types needed to cast spells or power their unique abilities: unholy, frost, and blood. The exact configuration of runes is customizable by players, although doing so will require you to go to a specific locale. We reckon this will work something like talents, in that you'll have to visit a trainer of some kind to let you respec your rune set up. It also seems like a player's rune configuration will vary based on the spell and ability types they favor.
