Do not interrupt the Frost death knight. Bait Anti-Magic Shell with a cheap spell, then stun. Save your kick for their healer, and stay out of Mind Freeze during Pillar of Frost.

Pillar of Frost after Death Grip into Chains of Ice is their kill. They drop Anti-Magic Zone on your go. Expect Anti-Magic Shell on your first magic crowd control.

Stop magic damage inside Anti-Magic Zone — drag the fight out. Do not dump spells into Anti-Magic Shell. Sit Icebound Fortitude or swap; Lichborne is a self-heal, keep chip.

Trinket Asphyxiate, not Chains of Ice. Death Grip pulls you into Remorseless Winter — do not stand at grip range on a pillar. Blinding Sleet is a disorient; spread if you can.

Go after Anti-Magic Zone expires and Icebound Fortitude is spent. After Frostwyrm's Fury with no kill they are often committed with no wall.

Dumping a full caster go into Anti-Magic Zone, or spending your only magic crowd control into Anti-Magic Shell.
