The Nurgle tech tree consists of technologies that unlock new advantages throughout the game. Research takes place constantly, but the rate at which discoveries occur can be increased by using heroes to spy or building additional research buildings at your settlements.

Nurgle's tech tree is divided by 7 tiers of technology with 7 techs each. To unlock a new tier, the player must at least research 4 techs from the previous tier of technology.

Tech tree[]

Description[]

Seven is the number of the Plague Lord. Seven are the ways which Nurgle infects mortal and immortal alike with contagions. Invoke His methods and become the blessed carrier.

Come to Grandfather
Though the Fly Lord broadly eschews the politicking of the Great Game, he will seek fleeting accord with Khorne or Slaanesh should it be to the detriment of Tzeentch, his despised rival.

Favourite Children

The Urfather loves each and every Nurgling dearly, be they long-lived shepherds of his Rot or fated to be a brief and messy existence as contagion-spreading catapult ammunition.

Morale.png Leadership: +4 for Nurglings units
Spore Diffusion

The decomposing mulch of Nurgle's garden breeds countless foul-smelling, ruinous fungi, which yield a rich bounty of noxious spores.

"Like a fly laying its eggs, keep warm... incubate."

Growth.png Growth: +10 in settlements with Temperate climates
Rot, Glorious Rot

Flesh is but one of Nurgle's churches. His sermons may also be preached within the mind, where pathogens strip all reason from their hosts. As madness reigns, the Urfather rejoices.

Though Nurgle's Rot is disease perfected, already His ultimate gift to existence, there remains scope for delightfully nauseating new augmentations.

The more minds that fall to glorious delirium of Grey Fever, and the more voices that gibber in senseless madness, the more fertile Nurgle's cankerous domain becomes.

Growth.png Population surplus: +1 for newly-captured settlements
Maddening Crowds
