Yesterday (4/2/04), Cryptic Studios showed us three new powers from the defender archetype. These included Transfusion (stealing endurance and gaining life back in the process), Summoning a lightning storm, and finally a psychic blast power (which deals psionic damage in a cone). Check out the official link below to get more details on these powers, as well as a few screenshots.
