Build Necromancer Death Ascension CoA
Death
plagues 17 DoT effects attrition

The plague specialization: seventeen distinct rot, plague, and decay effects make up the densest DoT kit in CoA.

Load every plague you have onto the target and let the attrition math close the fight — a maximally proactive playstyle where your damage was decided ten seconds ago.

Signature Spell
Crypt Plague

Damage from Crypt Swarm applies a stack of Crypt Plague, and Lichfrost applies two — a wound that ticks Plague damage every 2 seconds for 10 seconds, stacking up to 10 times (fresh applications don't refresh the duration).

Retail Feel

Closest analog is Unholy/Blood Death Knight with an Affliction Warlock veneer: like a Death Knight it runs on Runic Power and stacks diseases rather than casting direct heals — Flesh to Worms and Plague of Undeath are a disease engine, not an Atonement-style damage-to-healing loop. The DoT-stacking (Crypt Plague to its cap, Necrosis duration), spreading (Crypt Explosion, Pandemic), and disease-refresh (Virulency) layer is pure Affliction Warlock. With no external heal anywhere in the kit, it isn't mechanically close to any real allied-healer spec (Disc/Resto/Mistweaver/Holy/Preservation).

Role, tiers & resource

In both battlegrounds and arena you swing fights by blanketing targets with diseases, then spreading with Crypt Explosion and Virulency — but with no fear, root, banish, hard stun, or interrupt, your pressure is pure disease throughput, never control. You die when the enemy's burst lands before your diseases finish ramping.

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.

A stack-tracking rotation rather than a reflex one — Crypt Plague, Damnation, and Expunge all need active upkeep, plus a dual mana/Runic Power economy, so the difficulty comes from timers, not execution speed.

Leveling Guide

Solo/duo, stack Flesh to Worms and Plague of Undeath on the target, let a summon soak the melee while you refresh diseases with Virulency and spend Runic Power on Command spells (which apply Expunge) for the real damage.

In groups it's a sustained shadow/plague DoT-caster whose Command-spell debuffs (Expunge, Expediting Death) multiply raid damage on the target, plus Apothecary's Cauldron for party haste.

Expunge
Every later disease-scaling talent (Expediting Death, Lichplague, Waking Crypts) is a multiplier on the 'damage taken from your diseases' debuff Expunge applies — it's the engine the whole kit is built around.

Strengths & Weaknesses
Strengths
  • Deep disease-driven output: Rot Fetishist converts a share of your periodic damage into direct damage, Damnation and Plague Science amplify everything against low-health targets, and Virulency duplicates your entire disease stack — the fight snowballs the longer your DoTs stay up.
  • Self-sustaining Rotling engine: Muck Summoner and Wormfood spawn exploding Rotlings off your periodic damage and channel, adding free cleave and burst without spending any resource.
  • Strong multi-target swing potential: Crypt Explosion and Putricide's Formula spread Crypt Plague and Plague damage to nearby enemies, and Virulency duplicates the whole disease package — you can pressure an entire clustered pack, not just one target.
Weaknesses
  • No external heal exists anywhere in the kit — a duo partner gets the Apothecary's Cauldron haste buff but never a heal, and all of the spec's drain-healing only ever feeds your own health bar.
  • Dual-resource strain: core tools split across Runic Power (Command spenders, Expunge, Crypt Explosion) and heavy mana costs (Flesh to Worms, Lichplague, Plague of Undeath, Virulency) — both pools can run dry in a long fight.
  • Ramp-up dependent and thin on defense: nearly all damage is stack-based (Crypt Plague, Necrosis, Expunge), so you're weak in the opening seconds of a burst window, and there's no interrupt to fall back on against a stun chain — only the Bone Tithe shield (usable even while stunned) and a pre-placed Phylactery still function once the chain lands.
