Loved both The Scar and Perdido Street station! Ripe for stealing for RPG plots.
I statted up my take on the probability sword from the Scar, but hasn't been used yet.
Ooh! Let me give it a try!
Unique magic item and weapon. Similar to a shortsword, 1d6 S/P, 19-20/x2
When you attack once with the probability sword, it functions as if you had
attacked 20 times, rolling each of the numbers from one to twenty once at
your highest attack bonus.
For the blows falling in the weapon's threat range (19-20), roll to confirm
the critical normally.
You do not get iterative attacks with the probability sword. Rather, for each
additional attack you add +1 to your attack bonus. In addition, for each
additional attack you may split your blows between one additional opponent,
provided you are using a full attack action. Each opponent must suffer from
a sequential sequence of at least five blows; you can't designate the rolls of
18 and 20 to one creature and the rolls of 17 and 19 to another, for example.
Example: Johan has a base attack bonus of +6/+1, Str 16.
He attacks an orc in plate mail with AC 18. His attack bonus is 6+3(Str)+1(because
he has one iterative attack)=10.
Blows 1-7 miss the orc, glancing off its plate mail.
Blows 8-18 hit the orc, each one doing 1d6+3 damage.
Blows 19 and 20 hit the orc and require two additional rolls to confirm the
threat.
Because Johan has 2 attacks, if he were fighting 2 orcs he could designate
blows 1-12 against the first, and 13-20 against the second. The break point
may be chosen by the player.
The probability sword is an exotic weapon that requires a vastly different fighting
style, thus requires an exotic weapon proficiency to use without the -4 penalty to
hit. (See the Scar for explanatory flavor text).
If the wielder has improved critical (probability sword), then the threat range
increases to 17-20/x2. Additional weapon-specific feats such as weapon focus
and specialization may also be taken.
The Power Attack/Cleave/Great Cleave feat chain (and other similar feats)
cannot be used with the probability sword.
Special combat maoeuvers such as disarm and trip can be used, but do not
benefit from the sword's power.
Expertise works normally.
If the wielder has whirlwind attack, this feat allows him to freely designate the
targetsof his blows among all adjacent opponents (breaking the usual sequential restriction for iterative attacks).
The probability sword is a charged item, found with 80+2d20 charges. Each round
of combat using the swords power removes one charge. It cannot be recharged.
