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).

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.

Ranking updated on August 29, 2026

The tree the best players actually run. Read from the top 10 Death Necromancers in our player rankings for raids, of whom 3 have since switched specialisation and 1 had no usable record, leaving 6. 35 of its 50 talents are identical across all 6, so they agree on the bulk of it and part ways on the rest. This exact tree is run by the 4th ranked player. Recorded on 17 August 2026.

The 56 points are a fixed budget, so no tree can take everything. The most common picks left out of this one: Creeping Plagues 67 %, Reclaimed Life 67 %, Deadly Defense 67 %.

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