That’s it...

That’s it. I’m sick of all this “Masterwork Bastard Sword” bullshit that’s going on in the d20 system right now. Katanas deserve much better than that. Much, much better than that.
I should know what I’m talking about. I myself commissioned a genuine katana in Japan for 2,400,000 Yen (that’s about $20,000) and have been practicing with it for almost 2 years now. I can even cut slabs of solid steel with my katana.
Japanese smiths spend years working on a single katana and fold it up to a million times to produce the finest blades known to mankind.
Katanas are thrice as sharp as European swords and thrice as hard for that matter too. Anything a longsword can cut through, a katana can cut through better. I’m pretty sure a katana could easily bisect a knight wearing full plate with a simple vertical slash.
Ever wonder why medieval Europe never bothered conquering Japan? That’s right, they were too scared to fight the disciplined Samurai and their katanas of destruction. Even in World War II, American soldiers targeted the men with the katanas first because their killing power was feared and respected.
So what am I saying? Katanas are simply the best sword that the world has ever seen, and thus, require better stats in the d20 system. Here is the stat block I propose for Katanas:
(One-Handed Exotic Weapon) 1d12 Damage 19-20 x4 Crit +2 to hit and damage Counts as Masterwork
(Two-Handed Exotic Weapon) 2d10 Damage 17-20 x4 Crit +5 to hit and damage Counts as Masterwork
Now that seems a lot more representative of the cutting power of Katanas in real life, don’t you think?
tl;dr = Katanas need to do more damage in d20, see my new stat block.

Katanas are okay. They're functional and neat-looking swords but nothing special.

>Weaboos getting mad over the eastern equivalent of a saber

I know it's stale pasta, but it still never fails to amuse me.

Not this shit again.
Better rules for Katanas.
(One-handed weapon, martial)
25 gp; 1d6 (s); 1d8 (m); Crit range = 20 (x4); Range --; Weight 4 lbs; Type S; Special --
(Two-handed weapon, martial)
35 gp; 1d8 (s); 1d10 (m); Crit range = 20 (x4); Range --; Weight 6 lbs; Type S; Special --

Damage is the same as a sabre, because a Katana is basically a sabre.
Crit range is 20 (because they're not actually going to crit very often)
Crit damage is x4 (because when they do crit, they crit hard)
No Special qualities (because it's just a sword)

Now take your Weeaboo shit out of here.

Katanas are thrice as sharp as European swords and thrice as hard for that matter too.

And thrice as brittle
