It was formatted differently. And the numbers where inflated. But it's not exactly hard to translate.

5e
Flame Cyclone
As an action, Arcane power swirls around your blade and outward toward your enemies, engulfing them in an inferno. Each creature, excluding you, with in 15' must make a Reflex saving throw.
If they fail they take fire damage equal to 3d8+ your Swordmage level, or half as much on a successful save.
Once you use this ability you can not use it again until you take a short or long rest.
