Because of a tornado's very small { AREA of effect } and its relatively high SPEED when moving at ground level,
it is usu. quite easy for a group of PCs to get out of the direct path of the funnel cloud --
and this is definitely a case where discretion is the better part of valor.

If a character is somehow caught out in the open in the path of
a tornado, he faces death in two forms.
    * First, he will take 4d20 points of damage from being battered by whirling debris that is carried along by the tornado near ground level.
    * Second, he will be lifted 10-60 feet into the air (d6 x 10), carried along for 100-600 yards, and then dropped from that height --
    suffering falling damage in addition to any damage caused by the debris.

Characters are more likely to be caught in the path of a tornado
if it approaches them while they are inside a structure. If they are
taking refuge inside a structure during the lightning storm that
normally precedes and accompanies a tornado, there is a 1 in 6
chance (2 in 6 at night) that they will not notice an approaching
tornado until it is too late to leave the structure and seek other
shelter. If the tornado strikes the structure (which is entirely at the
DM’s discretion) and the structure is destroyed or damaged,
characters inside the structure will each take 3d10 points of damage
(if the structure is destroyed) or 3d6 points of damage (if it is
damaged) from falling and flying debris, and there is a 1 in 10
chance that a single character (determined at random) will be
lifted into the air by the tornado, suffering effects as described
above.

Table 7: TORNADO DAMAGE TO STRUCTURES

                                        Die Roll
Type of Structure 1 2 3 4 5 6
Light wooden D D X X X X
Heavy wooden - D D X X X
Earth - - D D X X
Wood and stone - - D D D X
Light stone - - - D D D
Heavy stone - - - - - D

Letter Codes
    -: No significant effect
    D: Damaged (deduct half of defensive point value, assess 3d6 damage to each occupant)
    X: Destroyed (reduce defensive point value to 0, assess 3d10 damage to each occupant)

The DM should determine into which category a
structure falls, and he may modify this table to account for especially
strong structures of a certain type. For instance, a heavy
wooden structure with metal-reinforced walls and beams would
be considerably sturdier than a heavy wooden structure without
such features. Any structure flimsier than “light wooden” (for example,
one constructed of canvas or animal skins) is automatically
destroyed if it is hit by a tornado.
