Build Felsworn Slayer Ascension CoA
Slayer
warglaives Demon Form fury builder

Slayer is warglaive artistry — fast physical strikes that feed Demonic Rage toward Demon Form. It's the bread-and-butter Felsworn DPS line: build rage, transform, shred. Fel shields baked into the kit give it surprising self-sufficiency.

Dancing Blades

Critical strikes with melee abilities trigger Dancing Blades, dealing off-hand weapon damage to up to 5 nearby enemies.

Retail Feel

Closest to a Fury Warrior chassis with Demon Hunter flavor grafted on. Felguard's Inner-Demon leech and its dodge/crit-damage window act as a self-sustain and burst engine, and Hateforged Barrier — a regenerating absorb — echoes Demon Hunter mitigation stacking. Fury Unleashed, a spinning glaive channel that speeds you up and cleaves nearby enemies, plays the Bladestorm role; Fury of the Illidari, a multi-target blink assault, is its signature mobility burst. Net result: a Fury-Warrior-tempo cleave bruiser with Demon Hunter self-leech and a channeled AoE spin.

It wins battleground fights by walking into the scrum and grinding people down — Felguard's Inner-Demon leech and Hateforged Barrier keep it standing while Chaotic and Oblivion stack damage. With no hard stun of its own, a good kiter can hold it at range once its burst windows are spent.

How is this number calculated?

World bosses only (Conquest of Azeroth has no instanced raid yet) — Snowgrave, Setis, Lord Kazzak, Azuregos, The Will of Soggoth, Kaldros Depthbreaker.

These numbers come from Ascension Logs’ public combat logs, not an in-house guess.

The index compares each spec to the median player — the one sitting exactly in the middle of the ranking — on the same boss and the same group format: 1.00 matches that median player, 1.40 means 40% more damage than them. Only each player’s best fight counts, never their average — otherwise a player posting fifty fights would count as much as fifty different players, and averaging would mostly reward beginners still learning the spec rather than those who’ve mastered it. The comparison always happens on the same boss and the same format: a two-minute fight and a seven-minute one aren’t comparable, and a flex raid doesn’t give the same support as a 25-man.

Tiers (S, A, B…) aren’t picked by hand: the cutoffs are calculated from the real spread of every measured spec. A spec under 15 distinct players or 30 fights isn't ranked at all, rather than given a made-up grade.

How is this number calculated?

Mythic dungeons only — Ascension CoA has no Mythic+ tier yet (216 tracked encounters).

These numbers come from Ascension Logs’ public combat logs, not an in-house guess.

The index compares each spec to the median player — the one sitting exactly in the middle of the ranking — on the same boss: 1.00 matches that median player, 1.40 means 40% more damage than them. Only each player’s best fight counts, never their average — otherwise a player posting fifty fights would count as much as fifty different players, and averaging would mostly reward beginners still learning the spec rather than those who’ve mastered it. The comparison always happens on the same boss: 92.4% of dungeon fights are played in 5-player groups, and splitting by group size as well would discard more usable damage rows (4.5% lost against 1.4% when comparing by boss alone) for zero additional publishable spec — group size is therefore not part of the comparison.

Tiers (S, A, B…) aren’t picked by hand: the cutoffs are calculated from the real spread of every measured Dungeon spec — this column has its own distribution, it doesn’t reuse Raid’s cutoffs. A spec under 15 distinct players or 30 fights isn't ranked at all, rather than given a made-up grade.

Each performance above links to its own real combat report. Ascension Logs, however, doesn’t offer a rankings page covering every Mythic dungeon — unlike Raid, there’s no « View the source rankings » button here.

The rotation looks simple on paper — Azzinoth's Assault into Annihilan Strike — but the real skill is timing: lining up Inner Demon windows with Fury Unleashed and Fury of the Illidari takes real combat awareness, not just following a macro.

Leveling Guide

Solo/duo leveling runs the Twin Slice/Annihilan Strike into Azzinoth's Assault Felfury loop, with Immolation Aura and Fury Unleashed for cleave packs, and Hateforged Barrier plus Skull of Gul'dan as the defensive cushion.

The bottom of the spec tree skips leveling-dead picks in favor of free stats — Spite's Agility and Felguard's haste aura. In groups it's a sustained single-target/cleave melee DPS that brings a haste aura and can lean on Illidari Barrier for extra raid mitigation.

Azzinoth's Assault
Azzinoth's Assault is the core Felfury spender the whole rotation is built around.

Rotation
  1. Core loop, shared across all three Felsworn specs — Demon Form, triggered at full Rage, charges your next Felstrike with a wide array of bonuses.
  2. Signature (Dancing Blades): critical strikes with melee abilities now trigger Dancing Blades, dealing off-hand weapon damage to up to 5 nearby enemies.

Strengths & Weaknesses
Strengths
  • Real in-combat self-sustain — while Inner Demon is up, Felguard heals you off your melee damage and Hateforged Barrier stacks a regenerating absorb, letting it grind an extended fight with little outside healing. It's window-gated, not a constant drain, so time your aggression to it.
  • Mitigation stacks straight into a burst window — Inner Demon's damage reduction, Pit Lord's Strength above 75% health, and True Self's dodge/crit-damage all layer up, while Fury Unleashed and Fury of the Illidari add a strong on-demand AoE and single-target spike — an unusually high anti-focus floor for a melee class.
  • Real stickiness against kiters and peels — Felhoof Charge (a Felfury-generating gap-closer) plus Reachwalker's healing dash keep it glued to a target and the crit/leech loop spinning.
Weaknesses
  • Pure melee with no ranged pressure and only short-range gap-closers — a competent kiter shuts down the entire crit/leech loop by staying at range.
  • Minimal active group utility — its contribution is passive auras plus an interrupt; its one ally shield has to be talented into, and it has no way to heal or dispel teammates. A self-sustaining bruiser, not a support.
  • Almost no hard CC — no reliable stun against players, so it leans on gap-closers and its own mitigation windows. Once its burst cooldowns are spent, it's back to baseline against the next wave.

Demanding to play well — form/stance swapping, a dual-resource system (Energy, Demonic Rage). Shared across all three Felsworn specs, not a Slayer-only quirk.
