Easy way is to go with "It doesn't matter"
Stupid way is go with BK+1.
Assuming you have 350 attack for TPing without the knife and you have fSTR=7,
Going with BK+1: 10/350 = ~2.8% increase
Going with Jambiya: (33+7)/(32+7) = ~2.5% increase
so yeah, 30k for 0.3% increase. It's totally up to you.
That's the easy answer, here is the slightly more detailed answer:
Me in Aquarius thread wrote:
At 350, 10 ATK is a straight 2.857% increase vs an EM or lower target. Against something T or higher, it'll be a stronger increase, but you'll generally have some buffs anyway.
Lolbri as they're affectionately called on these forums:
Increase can be calced this way:
(((360/327)-.35)/((350/327)-.35)))= 4.306% increase.
With min IV Dia II:
(((421/295)-.35)/((411/295)-.35)))= 3.260% increase.
On a tougher enemy(Abraxas
, who no one ever fights anymore):
(((360/367)-.40)/((350/367)-.40)))= 8.818% increase.
With Min IV Dia II:
(((421/330)-.40)/((411/330)-.40)))= 3.550% increase.
As you can see, the higher defense and level the target is, the more ATK helps you. As opposed to Jambiya, the base damage on Jambiya is ~ 1.449% total increase for DoT, and less on WS since it's only 1 hit. The 10 ATK from BK+1, however, will apply on WS as well, making it the better choice in general.
Out of curiosity, outside soloing DC/EP, where would a DNC have +7 fSTR?
I would get both and not bother with the CUK. With Joyeuse off-hand you will never notice a difference between the two, so use whichever you like.
Definitely ditch the CUK. It's a crappy dagger that only looks impressive because of low delay, but really doesn't help much. As for Joy, well, my opinions are pretty clear in this thread. Edited, Mar 13th 2009 2:31pm by Souji
