This guide will cover everything you need to know about playing Frost in PvE content. Frost is an extremely flexible spec providing good sustained damage on both single target, cleave, and AOE.
Mage continues to have a desirable progression spot due to the Arcane Intellect raid buff and its Ice Block immunity.
Strengths:
Good mobility, especially during micro movement.
Excellent 2-target cleave thanks to Splitting Ice.
Strong defensive kit.
Time Warp, Arcane Intellect, & the class tree provide a wide range of dungeon utility.
Strong consistent passive slows.
Drawbacks:
No spread AoE, execute or meaningful funnel damage.
Competes with the other mage specs for similar strengths.
Extremely low passive tankiness. Defensive kit is all proactive which requires spec comfort or encounter knowledge.
Main raid utility is Arcane Intellect which does not make stacking the class appealing.

The core mechanic of the spec is Shatter. Spells against enemies who are frozen benefit from Shatter, and have a greater chance of being struck a critical strike. Your critical strike chance against frozen enemies is:
(Critical Strike chance * 1.5) + 50%
The main way of gaining Shatter in PvE is through Winter's Chill via Flurry and Fingers Of Frost, with most rotational decisions involving maximising the number and effectiveness of both these abilities. During this guide I will refer to you causing a spell to gain the Shatter effect as ‘shattering’ that spell.
If a target has no Winter's Chill we can shatter 3 spells instead of 2 by casting either Frostbolt or Glacial Spike first and then following that cast up with a Flurry. We can do this because Flurry is three separate projectiles that each hit the target in sequence with a small delay. The Frostbolt or Glacial Spike will consume a stack from the first or second projectile, and the last Flurry projectile will refresh the stacks back to 2.
The frost mage rotation revolves around maximising the impact of your two procs, Brain Freeze and Fingers Of Frost, while maximising the number of these procs through casting Frostbolt and Frozen Orb.
A target is either frozen or not frozen, there is no additional damage benefit to casting a Fingers Of Frost Ice Lance into a Winter's Chill. However Casting a Fingers Of Frost Ice Lance into a target that already has Winter's Chill will not consume Winter's Chill.
Frostfire has three additional proccs.
Spellslinger has one additional proc.

The main gameplay loop of Frost in single target revolves around four abilities: Frostfire Bolt, Flurry, Ice Lance and Glacial Spike. The goal here is to maximise the amount of Glacial Spike that we cast and to shatter as many spells as possible.
All other spells like Ray of Frost, Comet Storm, Frozen Orb and Shifting Power are cooldowns that get woven inbetween the filler rotation at specific points in the Priority. Note that those also benefit from Winter's Chill, but do not consume any stacks.

Frostfire Bolt ➜ Icy Veins + Flurry ➜ Comet Storm ➜ Frozen Orb then follow the priority list below. Try to precast the Frostfire Bolt around 2 seconds before pull so it impacts together with the followup Flurry the moment the boss is engaged.

This rotation is specifically for 2 target Cleave. The key differences from the single target rotation include managing Frostfire Empowerment, the use of Blizzard when talented into both Ice Caller and Freezing Rain, and actively stacking Death's Chill during our main Icy Veins.
If you are currently casting Glacial Spike while your main target has Winter's Chill, you can swap to the second target during the Glacial Spike cast and queue another Flurry at the second target to shatter both cleaving Glacial Spikes. This only works when talented into Splitting Ice. Make sure to consume the Winter's Chill from your second target before swapping back.
Frostfire Bolt ➜ Icy Veins + Flurry ➜ Frostfire Bolt ➜ Frostfire Bolt then follow the priority list below. Try to precast the Frostfire Bolt around 2 seconds before pull so it impacts together with the followup Flurry the moment the boss is engaged.

AoE for Frost starts at 3+ targets. The priority list below assumes you have Comet Storm and at least one of Ice Caller or Freezing Rain talented.
Against freezable enemies if you have just cast Glacial Spike or Comet Storm, shatter those with your Water Elemental's Freeze and Ice Nova with high priority. Do not use Novas before, during, or right after casting Cone Of Cold, since Cone Of Cold already applies Winter's Chill by itself to all targets. Frost Nova is currently not worth using since it deals extremely low damage.
Blizzard ➜ Icy Veins + Frozen Orb then follow the priority list below. Try to precast the Blizzard around 2 seconds before pull so it impacts the moment the boss is engaged.
The following concepts should not be seen as a rigorous guide but rather what the idea of 'good gameplay' is based upon.
Doing nothing for an extended period of time in a fight will tank your DPS a lot more than doing some rotational mistakes.
Plan your movement and think in advance where you want to be when the next boss mechanic happens. Always move during your global cooldowns and make good use of Blink, Ice Floes and Alter Time.
Dont press your cooldowns blindly but also do not sit on them for too long. Timing them around certain boss events like damage amps or add spawns can sometimes be sensible.
While most of our defensive cooldowns are proactive we are one of the tankiest classes in the game when cycling through Ice Cold, Coldest Snap, Greater Invisibility, Mirror Image, Alter Time and Prismatic Barrier.
Frost stats weights are a little closer than some other specs, and due to the large Intellect stat budget on items, item level will usually be an upgrade. Stat weights vary depending on your current gear and talents. To produce an accurate stat priority or to accurately compare items you must sim yourself.
Generally for Frostfire, prioritise stats like so:
Generally for Spellslinger, prioritise stats like so:
With the high variety of available loot, enchants, gems and crafted gear there is a plethora of different gear combinations that will all match the highest possible DPS. Simming your character on Raidbots and simply equipping/aiming for what comes out of Top Gear and Droptimizer is the recommended and most sensible approach to gear your character.
While there is not one single set of BIS gear, there still are items that will be part of almost every individual BIS gear combination. Those are:
Because all active trinkets share a short cooldown with each other, we generally want to avoid equipping two active trinkets. Below is a list of good options for the current Season. For up to date trinket data please refer to the sims page of the site.
The following Embellishments are recommendations. Which of these you choose as your early crafts will vary based on your loot luck. Sim yourself for best results.
Frost generally has more impactful DPS racials than some of the other specs in the game. Utility racials still remain powerful and are worth consideration. For up to date racials data please refer to the sims page of the site.
HordeMacro Icy Veins, all usable equipment and all racials into one key. The numbers in /use 11, /use 12, ..., each refer to a certain equipment slot:
#showtooltip /cast Icy Veins /cast Blood Fury /cast Berserking /use 11 /use 12 /use 13 /use 14 /use 2
The macro below can be used to automatically cancel Ice Block if you try to cast a spell (Frostbolt in this example) while blocked. It also automatically targets something if you try to cast that spell with no target and [nochanneling] allows you to spam it without cancelling Shifting Power or Ray of Frost:
#showtooltip /cancelaura Ice Block /cast [nochanneling] Frostbolt /targetenemy [noexists][dead]
Automatically cast ground targeted abilities wherever your mouse cursor is, saving you a click. Example with Blizzard, works for all other ground targeted spells:
#showtooltip /cast [@cursor] Blizzard
Utilize a single keybind to cast Icy Veins and if Icy Veins happens to be up to cast Freeze at the mouse cursor location:
#showtooltip /cast [nopet] Icy Veins; [@cursor] Freeze
Can be used to cancel Ice Block and immediately Blink. Useful when Ice Blocked in a void zone as you'll Blink out and take no damage. Also works with Shimmer:
#showtooltip /cancelaura Ice Block /cast Blink
Counterspell. Prioritizes Mouseover > Focus > Target:
#showtooltip Counterspell /cast [@mouseover,harm][@focus,harm][harm] Counterspell
Spellsteal. Prioritizes Mouseover > Focus > Target:
#showtooltip Spellsteal /cast [@mouseover,harm][@focus,harm][harm] Spellsteal
Mouseover Remove Curse:
#showtooltip Remove Curse /cast [@mouseover]Remove Curse
Alter Time snapshots our current location and health. The spell can then be reactivated within 10 seconds to return us to said location and health. However if the buff expires we will be returned regardless, which sometimes we may not want to do.
If we cancel the Alter Time buff, it will not automatically be activated at the end of the duration, allowing us to stay where we are.
/cancelaura Alter Time
Why is there no checkbox for Death's Chill in the single target rotation?
We currently do not actively play around Death's Chill in single target and treat it as a passive.
What about the 'Boltspam' rotations from last season?
They are dead. And hopefully stay dead.
Is there a target count where we stop casting Glacial Spike in AoE?
No. Not until there are so many targets that every global cooldown is a Frozen Orb or Blizzard so the Glacial Spike doesnt get reached in the priority.
Do multiple Blizzard casts stack?
Yes. While the visuals are sometimes buggy, the damage does stack and so does the cooldown reduction for Frozen Orb.
As Frostfire do I need to track Frost Mastery and Fire Mastery?
No. We dont play around them.
Why do we cast Flurry when both Excess Fire and Excess Frost are up?
With Excess Fire our next Ice Lance will refund a Flurry charge by proccing Brain Freeze and grant another Excess Frost. Casting Flurry like this plays around both, not munching Excess Frost and not munching Brain Freeze. Note that this condition does not care about Winter's Chill but does respect Icicles in the priority.
When casting Glacial Spike into the last stack of Winter's Chill, can I queue an instant Frostfire Bolt when Frostfire Empowerment is up?
Yes. Both spells will impact at the same time and benefit from Winter's Chill.
As Spellslinger why do my Frost Splinter keep hitting random target dummies in Dornogal?
Splinter targeting is bugged on dummies. There are additional, isolated ones on the pillars right above where the other dummies in Dornogal are - practice on those instead..
As Spellslinger why is my Frost Splinter damage so low in Details, am I doing something wrong?
Logs and sims automatically combine most of the different splinter damage sources into one.
Why does Cold Snap not reset my Cone Of Cold?
The talent Coldest Snap disables all cooldown reductions for Cone Of Cold, including Cold Snap, Shifting Power and Time Manipulation.
Why does my Cone Of Cold not reset Comet Storm or Frozen Orb?
The talent Coldest Snap requires you to hit at least 3 targest for its effect.
How do I sim against freezable targets?
Paste your SimC output into Raidbots and scroll all the way down. Then enter target_level=80 into the "Custom APL and SimC Options" field.
How do I sim Mythic+?
There is no single sim that will represent a Mythic+ dungeon. Looking at the results of multiple Patchwerk sims with different numbers of targets and various settings can help you understand what is good in different situations. Note that very short sim durations and fight styles other than Patchwerk can be misleading and are therefore NOT recommended.
What stat percentages should I aim for?
Nothing, you don't aim for specific percentages of stats. There are very few stat breakpoints in the game that are of utmost importance, and any that are will be reflected in sims. You equip the gear that gives you the most DPS with almost no thought on what stat percentages that leaves you at.
Should I use Pawn?
No, it's an outdated addon, based on an outdated way of thinking about the game. It relies too heavily on stat weights being an accurate method of comparing gear, which they aren't. Just use top gear and never think about stat weights ever.
What should I set my Spell Queue Window to?
If you don't know why you're changing it leave it at the default (400). You can print out your current Spell Queue Window by entering this command /dump GetCVar("SpellQueueWindow") ingame.
Should I use Arcane Momentum?
Generally I would advise against it as it's more error prone and currently has multiple different bugs.
My sim says this thing gives X stat, but in game I get Y?
Raidbots takes it's tooltips from Wowhead. They may not necessarily lineup with the values being used by the sim. Always check the HTML report.
