Welcome to this week's Arcane Brilliance, the weekly mage column that insists that tragic teleportation accident that left you with a polearm instead of an actual arm does not entitle you to a refund.
Yeah, I should have known better than to start a multi-part leveling guide during a PTR cycle.
Barring more huge news, we'll come back to the leveling guide next week, but this week we need to discuss the fact that Deep Freeze is awesome. Don't believe me? Stop reading this right now. Download the PTR client. Transfer your mage over. Spec Frost. Go find a training dummy. Use Deep Freeze on it. Giggle. Then come back here, because holy crap.
Here's how the spell works currently on the PTR:
Deep Freeze: This spell now deals a large amount of damage to targets permanently immune to stuns.
The base damage is 1469 to 1741. The spellpower coefficient appears to be rock solid, something in the neighborhood of 2-2.5. It doesn't currently benefit from Ice Shards or get an increased crit chance from Shatter, but I expect both of those things to change before this goes live. When it hits the PTR, it'll be the single most powerful damage-dealing spell Frost mages have.
It'll be like a Pyroblast made of ice. Only better.
For those of you with a short attention span, here's the tl;dr version:
After patch 3.3 hits, in a raiding spell rotation, you will use Deep Freeze every time it's off cooldown, and you will see a substantial DPS increase because of it. Read on for the longer, more text-intensive version.
