Editing Katanas are Underpowered in d20 (section)

==Dadaos are Underpowered in d20==
That's it. I'm sick of all this "Katana easily bisecting knight" bullshit that's going on in the d20 system right now. Dadaos deserve much better than that. Much, much better than that.
I should know what I'm talking about. I myself commissioned a genuine dadao in PRC for 20,000 Yuan (that's about 2,400,000 Yen) and have been practicing with it for almost 2 years now. I can even chop slabs of high grade steel in two with my dadao.

Downtrodden Chinese smiths spend days working on a piece of railroad and shaping it up a few times to produce the finest sword known to all civilizations.

Dadaos are thrice as hard-hitting as katanas and thrice as durable for that matter too. Anything a katana can slice through, a dadao can slice through better. I'm pretty sure a dadao could easily behead three Japanese officers in a row while breaking their katanas at the same time with a simple horizontal swing.

Ever wonder why the Japanese Empire failed to conquer China? That's right, they wasted too much time trying to lure the skilled Chinese soldiers into field battles where their dadaos of devastation would be of little use. Even in Korean War, Capitalist artillerymen targeted any semblance of cover first because a counter-attack from men with dadaos would stagnate any offensive operation, if not outright blundering it.

So what am I saying? Dadaos 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 Dadaos:

(One-Handed Exotic Weapon)
2d6 Damage 
19-20 x2 Crit
+4 to hit and damage
Counts as Masterwork

(Two-Handed Exotic Weapon)
4d6 Damage
17-20 x2 Crit
+10 to hit and damage
Counts as Masterwork

Now that seems a lot more representative of the combat power of Dadaos in real life, don't you think?

tl;dr = Dadaos need to do more damage in d20, see my new stat block.
