In slightly longer form:
- Get brainfreeze proc.
- Cast EB/GS.
- Immediately cast flurry using the brainfreeze proc.
- Immediately shimmer towards the target.
- When the first flurry bolt launches, you are closer to your target than you were when you cast EB/GS.
- Flurry lands, winter's chill applied.
- GS/EB lands, shatters, subsequent flurry bolts land.
- Bask in the glory and admiration of your peers.
