I have noticed a few charms that have some variation of the same mechanics, but I don't understand why it is beneficial.
One example: Thousand Razor Wind (Dragon Blooded p278)
The mechanic lets you do more than one decisive attack against the same foe, and you then split the initiative damage pool among all the attacks rounding down.
My question is what makes this desirable? Or maybe in what cases/strategies would this be beneficial.
