UPDATED POWERS:

Holy Light: Both Paladins and Blood Knights are fueled by the same thing-- the Light. Holy magic is required to do almost anything except for the most of basic combat skills such as parrying or thrusting. What the Light grants its followers is the ability to wield its magic for the purpose of mending allies or harming enemies.

Arcane Torrent: Blood Elves thrive off of magic and need it to survive, they draw it from the world around them with or without meaning to. Liadrin can use this ability to mass-siphon energy from all those in the immediate vicinity, friend or foe, in one quick burst. This is a close range ability only.
