Arms Warrior Mythic+ Guide

• Slayer's Dominance
  • You attacks have a chance to proc Slayer's Strike, which applies Marked for Execution.
• Unrelenting Onslaught
  • Consuming Marked for Execution reduces the cooldown of Bladestorm.
  • You can use Storm Bolt while channeling Bladestorm because of this talent, and since Storm Bolt does some damage it is a DPS increase.
• Overwhelming Blades
  • Consuming Marked for Execution, getting a Reap the Storm proc or using Bladestorm applies Overwhelmed.
• Imminent Demise
  • Every third Slayer's Strike procs a Sudden Death. This Sudden Death that comes from Imminent Demise does not need you to have the talent Sudden Death selected.
• Opportunist and Slayer's Malice
  • With so much extra power invested in Overpower it takes a prominent role in your rotation.

• Swap Warbreaker for Blunt Instruments if you need single-target damage more than AoE.

Skarmorak

• Control your damage on Crystal Shards so that you don't get several stacks of Crystalline Eruption, but still kill them quickly.

Master Machinists Brokk and Dorlita

• Make sure to interrupt Molten Metal from Speaker Brokk.
