Rift: Planes of Telara? Well, first you should check out our exclusive hands-on, direct from Gamer Day II. After you've digested that, MMORPG.com has some interesting info regarding the newly announced Archon soul, a support specialist class that allows you to convert your opponent's strength and energy into usable magic.
Trion's new twist on the traditional mage archetype focuses on buffing friends and allies and is a formidable combatant in its own right. That said, the Archons can also be quite vulnerable, especially during the period just after they've infused allies with their life force (and just prior to feeding off an enemy to regain their strength). Check out some background lore as well as a few class particulars at MMORPG.com.
