Regarding special results for Impale An impale does twice the weapon’s normal rolled damage.
An impaling blow with a short spear does 2D6+2 damage
points, not the normal 1D6+1. If the impaling adventurer
has a damage bonus, it is rolled normally and added to the
damage—the damage bonus is not doubled. Any magical
addition to the damage is only added once.
If the impale is also a critical hit, then the maximum
possible impaling damage (14 points in the case of the short
spear) is done to the victim, to which is added any damage
bonus and any extra damage from spells.
and
Special resulsts for Slashing
The slashing weapon’s damage should be rolled normally
twice and both results added together. A slash with a
broadsword does 2D8+2 damage points, not the normal
1D8+1. If the slashing adventurer has a damage bonus, it
is rolled normally and added to the damage. Any magical
addition to the damage is only added once. If the slash is
also a critical hit, then the maximum possible damage (18
points in the case of the broadsword) is done to the victim
in that hit location.
Is there a reason for the change in language and discrepency between the descriptions?
