/* Deviation p99 SWADE
If a blast template misses, it deviates 1d6″
for thrown weapons (such as grenades) and
2d6″ for fired projectiles. Multiply by 2 if the
attack was made at Medium Range, 3 if Long,
and 4 for Extreme.

Next roll a d12 and read it like a clock
facing to determine the direction the missile
deviates. A weapon can never deviate more
than half the distance to the original target
(that keeps it from going behind the thrower).
