Flammable Tomb Kings and Tomb Princes have had their ancient bodies preserved through elaborate embalming ceremonies performed by their priests, and are wrapped in pitch-soaked bandages. Tomb Kings and Tomb Princes are Flammable (see p.114 of the Warhammer rulebook).
The Curse The model responsible for killing a Tomb King or Tomb Prince must immediately take a leadership test. If it fails the test, it must immediately take D6 wounds that cannot be saved. If it was a unit, randomize as shooting. If it was more than one unit, in a multiple combat, all units must take the the test as above.
