User blog comment:JmLyan/Elyra, the Hedron Mystic/@comment-8098035-20130412162845/@comment-7481207-20130412172138

About the Q, the hedron that is launched just represents the particle. The hedron is just a projectile and vanishes and then reappers just like the shuriken thing that sivir throws. I guess I should elaborate that a bit. Because of this, the location of the hedron is only important for her E, it has no impact on her Ulti nor her passive.

As for the hedron restore rate, that is not affected by cooldown reduction, as it is not a cooldown.

The Ulti's projectile speed is around the speed of other global ultis like Ashe's arrow, Draven's axe and Ezreal's Trueshot Barrage.
