Frost Mage

With Legion, Frost initially became the lackluster spec for Mages, only really useful in situations with constant 2 target cleave, thanks to Splitting Ice, weak on single target and virtually worthless in AoE situations. However, after several balancing passes, and changes to the other specs, Frost shifted into being the best single target spec in Nighthold and possibly going forward as well (as usual, things might and will change).

Save for specific legendary setups and short burst windows, Frost’s biggest weakness is doing large scale AoE damage. It’s therefore not advisable to run it in content where speed is a concern (lower level mythic keys).

Important Patch 7.2.5 Changes

• Thermal Void has been changed, instead of increasing the remaining duration of Icy Veins by 2 seconds every time you land a shattered Ice Lance, it will now only do so for 1 second, but also extends the base duration of Icy Veins by 10 seconds (making it 30 seconds base).
• Landing two shattered Ice Lances inside one Flurry is no longer feasible, as the time between Flurry projectiles now scales with haste (more haste results in faster projectile shooting). It is still possible to do it by using Shimmer at the right moment.
• Two new legendaries added:
  • Soul of the Archmage grants us access to Frozen Touch regardless of the selected talent.
  • Shattered Fragments of Sindragosa automatically casts a Comet Storm on the target after casting 20 Frostbolts or Flurrys.

New Tomb of Sargeras tier set

2p: After using Frozen Orb, your crit damage is increased by 20% for 10 seconds. This is a very decent set bonus, especially for Glacial Spike.

4p: Any time your Brain Freeze procs, the remaining cooldown on Frozen Orb is reduced by 5 seconds. This directly boosts the 2p and is directly improved by T19 2p.
