B-TIER | BUILD FELSWORN SLAYER (@ascensionsidekick) | ASCENSION CoA

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.

How is this number calculated?

Measured scope: Zul'Gurub, Molten Core, Onyxia's Lair, all difficulties — High Priest Venoxis, High Priestess Jeklik, High Priestess Mar'li, Bloodlord Mandokir, High Priest Thekal, High Priestess Arlokk, Jin'do the Hexxer, Hakkar, Gri'lek, Gahz'ranka, Lucifron, Magmadar, Gehennas, Baron Geddon, Garr, Shazzrah, Golemagg the Incinerator, Sulfuron Harbinger, Majordomo Executus, Ragnaros, Basalthane, Onyxia.

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 (220 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.

Ranking updated on August 29, 2026

The tree the best players actually run. Read from the top 10 Slayer Felsworns in our player rankings for raids, of whom 1 has since switched specialisation and 4 were last recorded in a dungeon, leaving 5. 39 of its 51 talents are identical across all 5, so they agree on the bulk of it and part ways on the rest. This exact tree is run by the 9th ranked player. Recorded on 18 August 2026.

The 56 points are a fixed budget, so no tree can take everything. The most common picks left out of this one: Focused Hatred 60 %, Gul’dan’s Gift 60 %, Fel Blades 60 %.

These talents are a PvE configuration. The Arena and Battleground grades shown above rate the specialisation’s PvP potential, not this tree.
