Arms Warrior Guide
Arms is Midnight's reliable two-target cleave and burst-window melee. Everything funnels into the Colossus Smash debuff: line up Avatar, your big channel (Bladestorm or Demolish), and your procs inside that window and the spec hits hard and very consistently. It sits at A-tier in both raid and M+ because its 2-target cleave (Sweeping Strikes) and AoE (Bladestorm / Demolish) are strong without being fiddly, and the Master of Warfare apex talent plus deep hero trees add real depth for players who push optimization.
As of Patch 12.0.5, the Nebulous Voidcore lets you target gear via Bonus Loot rolls after Season 1 Raid bosses, Mythic+ dungeons, Bountiful Delves, and Nightmare Prey Hunts — a controlled way to chase Arms BiS instead of waiting on the Vault. A Bonus Roll after a M+ dungeon awards the Great Vault item level for that keystone level, so +10 and above can drop 1/6 Myth-track pieces. Weight your weekly cores toward the top raid trinkets (your BiS trinket, Heart of Ancient Hunger) and the Rage of the Night Ender tier 4pc; since secondary values converge and item level almost always wins, raw ilvl upgrades make most rolls worthwhile.

🚀 Opener
The whole opener exists to dump everything into the first Colossus Smash window. Pre-cast Rend, then fire Avatar + Ravager into Colossus Smash and spend your big channel and procs while the debuff is up. Slayer leans on Bladestorm; Colossus leans on Demolish at 10 Colossal Might.
- Charge into the boss/pull
- Avatar (line it up with Colossus Smash)
- Rend to apply the bleed
- Ravager just before Colossus Smash
- Colossus Smash
- Bladestorm (Slayer) inside the window
- Mortal Strike
- Demolish (Colossus, at 10 Colossal Might)
- Overpower
- Execute on any Sudden Death proc
- Fall into the single-target priority below
⚔️ Single-Target Priority
Goal: fill every GCD, keep Mortal Strike on cooldown, spend procs, and avoid both Rage starvation and overcapping. Everything is sequenced to land inside the Colossus Smash debuff.
- Keep Rend up (refresh under ~5s remaining)
- Avatar on cooldown (aligned with Colossus Smash)
- Ravager just before Colossus Smash
- Colossus Smash on cooldown
- Demolish during Colossus Smash (Colossus)
- Bladestorm during Colossus Smash (Slayer)
- Mortal Strike on cooldown
- Heroic Strike / Slam via Master of Warfare proc
- Overpower (don't overcap charges)
- Execute on Sudden Death procs (and in execute range below 35% HP)
- Slam as the Rage-dump filler
💥 AoE / Multi-Target Priority
Two-target cleave runs through Sweeping Strikes (mirrors your strikes onto a second target); 3+ targets shift Slam to Cleave and lean harder on Bladestorm/Demolish. Open every pack with Avatar + Colossus Smash so the burst lands in the debuff window.
- Keep Rend applied on the primary target
- Maintain Sweeping Strikes charges (Broad Strokes can auto-trigger it off Colossus Smash)
- Ravager before Colossus Smash
- Avatar with/before Colossus Smash
- Colossus Smash
- Bladestorm in the window
- Demolish during Colossus Smash (Colossus, at 10 Colossal Might)
- Execute on Sudden Death procs
- Cleave as the primary multi-target filler (3+ targets)
- Overpower, then Mortal Strike
- Refresh Rend when it falls off
⏱️ Cooldowns
Arms is a burst-window spec: stack your cooldowns inside Colossus Smash rather than spreading them out. Avatar and Colossus Smash are pulled into alignment by Anger Management (Rage spending reduces their cooldowns), so they naturally pair up over a fight.
💚 Defensive Toolkit
Arms is not immortal, but the kit is deep: a parry wall, a magic-eating reflect, a stance, a battle-rez-of-your-own-health Victory, and a raid-wide cooldown. Pre-press for known damage rather than reacting late.
🧰 Utility & Crowd Control
| Ability | Use |
|---|---|
| Pummel | Primary interrupt (~15s CD). Use a mouseover/focus macro. |
| Storm Bolt | Single-target stun (talent) — backup interrupt / lockdown. |
| Intimidating Shout | AoE fear — emergency pack control or to peel off you. |
| Piercing Howl | AoE slow around you — kite and gather support. |
| Heroic Leap | Gap-closer / repositioning leap; also a soft survival tool to exit ground effects. |
| Intervene | Charge to an ally and absorb the next hit for them — mobility + a peel. |
| Charge | Core engage; stuns/roots on impact depending on talents. |
| Shattering Throw / Wrecking Throw | Ranged tool — Wrecking Throw chews through absorb shields (huge multiplier). |
📊 Stat Priority
Stat priority (both hero trees share it): Item Level / Strength > Critical Strike > Haste > Mastery > Versatility. There is no variance between Slayer and Colossus — gear them the same.
- Critical Strike — generally your strongest secondary; powers Impale-style crit damage and proc generation.
- Haste — more GCDs and faster Rage = a smoother rotation, very close to Crit.
- Mastery / Versatility — solid but trail the top two; Vers also adds a little survivability.
Diminishing-returns starts (rating): Crit / Mastery first DR at ~1,380; Haste first DR at ~1,320. Higher item level beats gaming these breakpoints.
🎁 Tier Set, Trinkets & Consumables
Tier set — Rage of the Night Ender:
- 2-piece — Mortal Strike and Cleave deal +5% damage, and Colossus Smash increases damage taken by an additional 5%.
- 4-piece — Mortal Strike or Cleave on a Colossus-Smashed target (Cleave must hit 3+) extends the Colossus Smash debuff by 1.0s.
Top trinkets (raid): Gaze of the Alnseer and Heart of Ancient Hunger (top tier); Umbral Plume, Radiant Plume, Crucible of Erratic Energies as strong alternates. M+ alts: Algeth'ar Puzzle Box, Solarflare Prism.
Consumables: Flask of the Blood Knights (or Flask of the Shattered Sun) · combat potion Potion of Recklessness · food Harandar Celebration · Void-Touched Augment Rune. Gems: Flawless Quick Garnet (Haste) / crit-stat variants per your secondary needs. Enchants: weapon Jan'alai's Precision · rings Eyes of the Eagle · cloak Arcanoweave Lining · boots Lynx's Dexterity · chest Mark of the Worldsoul.
🗝️ Mythic+ Tips
- Run Colossus for dungeons — Demolish + bleeds + Sweeping Strikes give you the better sustained AoE; Slayer is the raid/ST pick.
- Open every pack with Avatar + Colossus Smash so your Bladestorm/Demolish burst all lands inside the debuff window.
- Keep Sweeping Strikes up for 2-target priority cleave; let it auto-trigger off Colossus Smash with Broad Strokes when specced.
- Charge or Heroic Leap between packs to keep uptime; lost melee uptime is lost damage with no Stagger-style smoothing to fall back on.
- Spread your interrupt load: Pummel + Storm Bolt + Intimidating Shout cover far more casts than a kick alone.
- Pre-press Defensive Stance / Spell Reflection / Die by the Sword for known unavoidable hits, and call Rallying Cry for group-wide spikes.
⌨️ Macros & Addons
WeakAuras is not supported in Midnight (12.0) — use Blizzard's built-in Cooldown Manager (import configs from Wago.io). Addons: ElvUI, DBM/BigWigs, OmniCD, Hekili (for priority help).

🚫 Common Mistakes
- Using Bladestorm / Demolish / Mortal Strike OUTSIDE the Colossus Smash window — almost all your burst should land while the debuff is up.
- Letting Rend fall off — it's a small but constant loss and several effects key off it.
- Overcapping Rage (or starving yourself) — keep filling GCDs with Slam/Overpower so spending stays smooth and Anger Management keeps reducing your cooldowns.
- Sitting on Overpower charges or wasting Sudden Death Execute procs.
- Holding Avatar for a 'perfect' window so long that you lose a full use over the fight — use it roughly on cooldown, aligned with Colossus Smash.
- Looking for Warbreaker or Thunderous Roar — those buttons were removed in Midnight; your AoE is Bladestorm, Ravager, Cleave and Demolish now.
- Forgetting your defensives — Die by the Sword, Spell Reflection and Rallying Cry are free survival/raid value if you pre-press them.
