Criteria:
Defeat Telash Greywing after using Icy Devastator 12 times on an Icy Crystal to create a Very Icy Crystal in The Azure Vault on Mythic difficulty.

Strategy:
This achievement is one of the easier ones, as long as you bait frost traps intelligently. Before engaging the boss, make note of where the blue floating crystal is. Once located, you can place a marker if it makes it easier to spot, but you will want every player to bait Icy Devestator on top of it. Each channel of Icy Devestator has four ticks, and this is why you want to be on top of the crystal before the cast goes out. If you manage to get all four ticks, you can complete this achievement in three casts of Icy Devestator. It is important to not cover the ground in ice with the Frost Bomb mechanic, so it is recommended that players bait this away from the crystal; however, the damage is not too terrible depending on your group's gear level. The most important thing to remember is getting all four ticks of Icy Devastator on the crystal. Once the crystal has 12 stacks, defeat the boss as normal.

The crystal is none click-able and none-target at first, but it will become a named unit can mouseover once you [spell=387151] it.
Each [spell=387151] channling cast have 4 tick, you can get [spell=391730] after crystal soak 12 ticks.

Greywing will cast [spell=387151] after [spell=386910] and timer is compact, its annoying because frozen ground can grow up quickly, so we decided do not avoid frozen ground damage, lust for healers, finish [spell=391730] as soon as we can.

Icy crystal > [spell=391461] > [spell=391728] > [spell=391729] > [spell=391730]
