A-TIER | BUILD FELSWORN INFERNAL (@ascensionsidekick) | ASCENSION CoA

Build Felsworn Infernal Ascension CoA
Infernal
fel magic Felstrike procs hybrid caster

Infernal is the caster-leaning Felsworn line — a Fire and Shadow school mix built around annihilation through fel magic.

It is a pure ranged Felfury builder-spender: Fel Fireball is your filler, and it auto-procs Felstrikes on its own. You do not plan this rotation so much as react to what the fel hands you.

Fel Apprentice

While Inner Demon is active, your Fel Fireball unleashes a Felstrike on your target — a Shadowflame burn over 6 seconds, stacking 3 times.

Retail Feel

The closest retail flavor is Warlock with Demon Hunter trim, but mechanically it stands on its own. The Inner Demon window plays like a timed Metamorphosis power spike, upgrading the riders on your spenders — Fel Fireball unleashes a Felstrike, Ruin gains a damage-over-time tail, Felwrath punishes packed groups harder — and the Infernal drop mirrors Warlock's summoned-add burst. Everything else diverges: this is a ranged Felfury builder-spender driven off Spell Power, and its self-healing is drain-flavored and thin — an effect that converts a target's burned mana into health for you, closer to a Drain Life than a real defensive, backed only by the class kit's Hateforged Barrier absorb, so don't expect Warlock-grade sustain. No retail spec maps to it as a healer, and any 'support' billing is flavor the kit doesn't back up — its real group contribution is the passive Fel Infusion party and raid crit buff, AoE burst, and the fear-lock on Infernal.

How is this number calculated?

Measured scope: Zul'Gurub, 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.

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 (229 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.

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

PvP
Resilience Stamina Spirit Critical Strike Intellect Haste

The spec is now a pure ranged Felfury builder-spender — no manual melee, Felstrikes proc automatically off your Fel Fireball casts. Spirit leads because it is not just a regen stat here: Hidden Power converts both Intellect and Spirit into spell damage, and Nether Spirit converts it into crit, making it a genuine throughput stat. Keep Spell Hit capped first, then follow Spirit > Critical Strike > Intellect > Haste (bisbeard weights: Spirit ~2.17 clearly dominant, Crit ~1.3 ahead of Intellect ~0.66).
