Plague

Plague is a status effect that can spread through combat. Any province — including Undead — can catch it. Spread occurs through both attacking and defending.

Immunity

Immunity prevents the penalties below and suppresses the plague indicator on the Throne page, but does not prevent a province from carrying or spreading plague.

Undead normally always carry plague invisibly: they ignore its effects and spread it at the base rate. All other races that contract plague spread it only at a reduced rate, which lowers transmission frequency but not plague strength.

Effects

  • No Population Growth
  • −15% Income (applied as −15% Tax Collection)
  • −15% Defensive Military Effectiveness
  • −10% Offensive Military Effectiveness

Curing Plague

  • Nature's Blessing: 33% chance to cure plague on each successful cast (and once per tick while active).
  • Hospitals: Daily cure chance of ~3% base, scaling with Building Efficiency up to a maximum of 75%.
    • At 100%+ BE, 25% Hospitals achieves the maximum cure chance.
    • At lower BE, a higher proportion of Hospitals is required.
