Q: Bladed Hand/Blade-Hand/Nekode/Neko-de + Karate gives damage comparable to, or better than, a Broadsword! What gives?
A: The damage bonus from Karate to fist/hand weapons
might be exaggerated.
If this is how you feel, remove the damage bonus from
swing damage of fist/hand weapons. The short version: Knock footnote [4] off the first line on the table for the bladed hand.
