Damage from Collisions

An object or person’s Hit Points
and velocity determine collision dam-
age. Mass only matters indirectly:
massive objects usually have high HP,
but it would hurt more to collide with
a locomotive than with a pillow of the
same mass! HP take into account both
mass and structural strength.
“Velocity” is how fast the character
or object is moving in yards per sec-
ond (2 mph = 1 yard per second).
Velocity could be anything up to
Move. It might exceed Move when div-
ing
or
falling;
see
High-Speed
Movement (p. 394).
An object in a collision inflicts
dice of crushing damage equal to (HP
¥ velocity)/100. If this is less than 1d,
treat fractions up to 0.25 as 1d-3,
fractions up to 0.5 as 1d-2, and any
larger fraction as 1d-1. Otherwise,
round fractions of 0.5 or more up to a
full die.
If an object is bullet-shaped, sharp,
or spiked, it does half damage, but this
damage is piercing, cutting, or impal-
ing, rather than crushing.
