Frozen Orb

Launches an orb of swirling ice which rapidly moves forward over [d]. While it is moving, every [t] sec the orb deals ${[m2]*$<power>/100*$<frostdamage>} Frost Damage and applies a Chill for [s1]% movement speed reduction to all enemies it passes through. The first time it damages an enemy, its movement will slow and it will have a 100% chance to trigger the Fingers of Frost rune.
