Mmm.... I've been thinking about it.
I really dislike the way most fantasy RPGs mix and match arms from different - often incompatible - eras and settings.
I mean... you get the paladin toting a XIII cent. bastard sword, the elven rogue is wielding an early 1600s rapier, the dwarf is trolling about a swiss axe from the late XIV... and most of them are wearing plate mail, designed to stop arquebus bullets [or are they pellets?], when gunpowder is none but unheard of in most fantasy worlds.
More on that! They misname the weapons too!
Let me rant on that forsaken rapier, pretty please!
So, let me shed some light. It is no rapier. Not even a cousin of it. What most RPGs are actually portraying is a foil, or more often than not, the little known ancestor, the colichermard.
Just google it, you'll find the sources I am quoting.
The rapier was by no means flexible nor light. It was derived by straight swords, not too unlike the scottish claymore [the smaller version, not the two-handed mehemoth] or the slavic schiavona.
While it was meant to strike by a thrusting motion, it was too heavy and unwieldy for close fencing in the true term.
That's why many warriors employed a second weapon in their spare hand - even if it only was a thick glove to parry slashes with.
Most rapiers were meant to gain advantage by reach over strenght: you could nail your opponent in his throat or groin, while he was still flailing his thicker, sharper and heavier broadsword to lop you head off with.
Of course, as it gained renown, people ditched older weapons; firearms had rendered them pointless by the previous century anyway.
So, swordplay became a closer affair, and thick weapons, meant to parry high-mass slashing blades [something still rare back then, though] got thinner and slimmer.
The first child to the rapier was the hybrid "colichemard". It had a thicker lower section, meant to counteract the ticker rapier, and a lighter striking point, which helped quick forward leaps.
As more warriors moved on to the colichemard, smiths further refined it, and ditched the rectangular section, for a full diamond shaped foil blade.
The sword most RPGs mistake for a rapier!
That is something that really bugs me!
And the rapier would be too heavy to rely on DEX anyway! So there, dual-wielding finesse fighters!
Try an estoc next time! At least you won't look like some lost-in-time D'artagnan wanna-be!
