The Tome of Decay (2014), p48 — Unleash the Foetid Footman

Plague Cults often summon Plaguebearers to help them in the spreading of disease and corruption. Obsessed with counting and cataloguing every contagion ever created, Plaguebearers welcome any chance to push through to the mortal realm.

Requirements: The ritual must take place in an area touched by disease and the stench of death, and requires a roughly carved circle marked with icons devoted to Nurgle while cauldrons of putrid bubbling liquids fill the entire area with a horrid stench. Rotting corpses - they needn't be human - should form a pile at the centre. A single adult human, their body untouched by disease or illness, should sit atop the pile of corpses, ready to absorb all the filth and become the window through which the Plaguebearer emerges. The ritual requires a Hard (-20) Forbidden Lore (Daemonology) Test, modified per Table 6-7: Summoning Ritual Modifiers (see page 229 of the Black Crusade Core Rulebook). If successful, then the Heretic must make a Daemonic Mastery Test to control the Plaguebearer.

Effects: A Plaguebearer (see page 355-356 of the Black Crusade Core Rulebook) appears in the summoning circle.

Duration: The Plaguebearer remains corporeal for 1d5+5 rounds, plus an additional round for every additional Degree of Success on the Test. Areas where the veil between reality and the Warp is thin might extend this duration. Heretics may summon the Daemon for a specific task (at the GM's discretion), in which case it remains corporeal long enough to accomplish the task.

Cost: Whether successful or not, the Heretic must roll on Table 6-2: Psychic Phenomena (see page 210 of the Black Crusade Core Rulebook) and immediately apply the results. Additionally, each character involved in the ritual must pass a Challenging (+0) Toughness Test or gain 1d5 levels of Fatigue, doubling over and choking on the waves of smog and clouds of flies that accompany the Daemon's arrival.

The Price of Failure: Failure results in a roll for Contempt of the Warp (see page 227 of the Black Crusade Core Rulebook), modified by +10 for every Degree of Failure beyond the first.
