Parrying Heavy Weapons

You cannot use a flimsy rapier to parry a titan’s tree-
sized club, the slam of a charging linebacker, or the
sword of a giant robot! Heavy weapons are liable to
knock your weapon away – or even break it.
The same is true for unarmed attacks from high-ST
creatures. For the purpose of these rules, treat a punch,
kick, bite, etc. as a weapon with an effective weight of
1/10 the attacker’s ST. Use his full ST if he made a slam,
flying tackle, pounce, or shield rush!
Your weapon may break if it parries anything three
or more times its own weight. (This does not apply to
barehanded parries; for damage to limbs when parry-
ing unarmed, see Parrying Unarmed.)
A weapon parrying three times its own weight has a
2 in 6 chance of breaking: it breaks on a roll of 1 or 2
on 1d. Add +1 to these odds per whole-numbered mul-
tiple past 3 (a 3 in 6 chance at 4 times weapon weight,
a 4 in 6 chance at 5 times, and so on). Weapon quality
