Hmm?! Better? Gods, a monk's fist is clearly one of the best weapons in the game at HIGH levels. And don't forget, you have to pay for the great damage - you won't have any special bonuses like elemental damage or stun attacks. CF on the other hand is one of the best weapons in the game WITHOUT any buffs - it stuns targets at failed save, deals electrical damage... now you'd impove this further by increasing the Criticals to x3(!!!) and adding more attacks/round..?you forgot that Shed wants to make Yikari to be better with Celestial Fury than with his fists
Frankly, you are right - this will be much better than any normal (legal!) monk using fists. Is this a good thing? You decide.
