Greenflame blade

Greenflame blade is a transmutation spell most often used by assault swordmages, though swordmages of other styles are also known to cast it. When cast greenflame blade ignites the swordmage's weapon with viridian flames, which add to the deadliness of the swordmage's attacks for an instant. Greenflame blade, which can be cast at will uses the swordmage's intellect and physical strength as the basis for its power, though a swordmage of greater experience will cast a significantly more powerful version of the spell.
