Some creatures can breathe fire, such as dragons, and some war machines can project flames, such as a Skaven warpfire thrower. Buildings are vulnerable to fire because they are often made from wood and contain furnishings and floor coverings which are easily burned.

When attacking a building with a fire weapon, add the score of a D6 to the weapon's strength to represent the slightly unpredictable incinerating effect of the flames. Work out damage as normal.

If you roll a 6 when you roll for extra strength the building also catches fire. This is regardless of whether the hit also causes damage. A burning building sustains 1 extra damage point at the start of every turn from now on (ie at the start of each player's turn). Once all of its damage points are gone the building is destroyed.
