Frost Death Knight Season 3 Mythic Plus Guide -

Strengths and Weaknesses

Frost Death Knights are unique because they can do really strong damage to both bosses and groups of enemies. A huge part of why they perform well in Mythic Plus is because they can survive hits that would easily kill other classes.

Their defensive tools make them tough to take down, and they also bring excellent enemy control through grips and slows, keeping fights organized for the group.

Some of the best defensive and control tools that Frost DKs have include:

Ability	Effect
Icebound Fortitude	Reduces damage taken and prevents stuns.
Anti-Magic Shell	Blocks harmful magic and prevents magic debuffs.
Death Strike	Heals based on recent damage taken.
Lichborne + Unholy Endurance	Grants immunity to certain effects and increases survivability.

When it comes to helping the group, Frost DKs have some very handy abilities:

Group Utility	Function
Mind Freeze	A quick interrupt, even usable at range.
Blinding Sleet	Stops groups of enemies from casting.
Death Grip	Pulls a single enemy directly to you, helping tanks with positioning.

Even though Frost DKs are strong and reliable, they do have a few weaknesses.
They don’t offer much in the way of unique group utility — they can’t provide Bloodlust or Invisibility.
However, they make up for this with mob control and a battle resurrection, which is often enough to secure a spot in a Mythic Plus group.

Overview — How Frost DK Works

Frost DK is all about managing two main resources: Runes and Runic Power.
You use Runes to cast big abilities like Obliterate or Frostscythe, and those attacks build up Runic Power. Then, you spend that power on abilities like Frost Strike or Glacial Advance, which refresh your runes faster.

It’s basically a cycle — you spend one resource to build the other, and keeping that balance is key to doing strong damage.

Along the way, you’ll get random procs that make your attacks even stronger. The most important ones are:

Proc	Effect
Killing Machine	Makes your next Obliterate or Frostscythe a guaranteed critical hit.
Rime	Makes your next Howling Blast free to use and deal extra damage.

Knowing when to use these procs is a huge part of mastering Frost.

Talents and Dungeon Choices

Mythic Plus Frost DK has a flexible talent tree, letting you pick both strong damage and defensive options without losing much.

For example:

Talent	Benefit
Vestigial Shell	Gives you a small defensive shield.
Unyielding Will	Removes harmful magic effects.
Fixate	Adds a short single-target stun for extra control.

Your basic build will work well in nearly every dungeon, but you can adjust small parts of it for certain situations.

In Priory of the Sacred Flame, Control Undead lets you take over certain mobs to stop dangerous spells.
In Streets of Wonder and Halls of Atonement, Cold Thirst helps you use Mind Freeze more often.
During seasonal effects like Zata’s Bargain, Blinding Sleet becomes your best tool because it’s your only big AoE stop.

Combine Blinding Sleet, Mind Freeze, and Death Grip to stop deadly casts and control the battlefield.

Single Target Rotation

When facing a single boss or strong target, your goal is to use every ability efficiently and avoid resource overflow.

At the start of a fight:

Use Empower Rune Weapon to prevent running out of runes and build Runic Power quickly.
Then, activate Frostwyrm’s Fury and Pillar of Frost to begin your burst phase.

After that:

Use Obliterate when Killing Machine is active or has two stacks.
If you get a Rime proc, use Howling Blast right away.
When you have extra Runic Power, use Frost Strike (unless Breath of Sindragosa is almost off cooldown).

Keep your resources flowing — spend Runes with Obliterate and Runic Power with Frost Strike.

Priority Order (Single Target)
1. Killing Machine → Obliterate
2. Rime → Howling Blast
3. Runic Power near full → Frost Strike
4. Cooldowns → Pillar of Frost + Empower Rune Weapon

If Pillar of Frost is nearly ready, save a few runes to start your next burst right away.
Always try to pair Pillar of Frost with an ability like Frost Strike, Glacial Advance, or Howling Blast to trigger Killing Machine immediately.

AoE Rotation

When you’re fighting large groups of enemies, your rotation changes slightly — but the idea stays the same.

Instead of Obliterate, use Frostscythe, which hits every target around you.
When Killing Machine procs, Frostscythe becomes one of your hardest-hitting abilities.

Start big pulls with:

Empower Rune Weapon
Pillar of Frost
Frostwyrm’s Fury

Then:

Use Frostscythe with Killing Machine.
Use Howling Blast when Rime procs.
Spend Runic Power on Glacial Advance to fire icy spikes and maintain Razorice stacks.

AoE Tips	Why It Matters
Keep Razorice stacked	Boosts all frost damage on enemies.
Avoid switching targets too fast	Prevents losing your Razorice stacks.
Use Pillar of Frost often	Keeps damage consistent across pulls.

When you run low on Runes, spend Runic Power with Glacial Advance or Frost Strike.
Then, go back to Frostscythe once your Runes return.
Your cooldowns should align just like they do in single-target fights — use Pillar of Frost whenever it’s ready, and keep your resource flow steady.

Final Thoughts

Overall, Frost Death Knights are solid, dependable, and fun to play in Mythic Plus.
You may not bring flashy or unique group utility, but what you do bring is consistent damage, control, and toughness — all of which make you a valuable part of any team.
