the only problem with this knife is the dmg. yes, it is amazing for getting TP very fast, if u can land any dmg. I am a thf, and i have a harpe subbed hornetneedle. with my main hand, i hit for about 40 dmg and with my sub i hit for ****, maybe 15 on ITs. now keep in mind hornetneedle's dmg is 16, this dmg is 8. i believe that if u were to take this to an EXP pt as a thf, ud be wasting ur time hitting for 0s. on the other hand tho, it would be nice for soloing as a thf because most of our soloing dmg comes from dancing edge and sneak attack, even if u hit for 1 dmg three times, thats 15 TP+5 more from ur main hand. and then, of course, theres always a chance of triple attack giving u a maximum of 60 tp in a single attack round!
actually, 30tp is the max, even with this knife, "occasionally attacks 2-3 times" does not stack with triple attack, either one or the other would go off, which is a little disappointing, but understandable in the same right
