@duriel123: it happens ^_^
@Wubzey Aristocratan there's no ideal ratio. and what the person's actual ratio is entirely dependent on their Total Stat/Total Watk (w/ or w/o pot depending on how/what you want to compare). but helpful link http://i.imgur.com/l6vgG4G.png. 1:7 is kinda bad...

[quote=GoXDS]@duriel123 the AB shouldn't be squared[/quote]
An embarrassing algebra mistake, hehehe......

@Aristocratan: I think its something like 1Atk to 7-10 luk?

@GoXDS: ok that is much easier to understand, though still a bit confusing but understandable <3

@janny1993 if you had X Main Stat and Y Atk, simplified formula gives your range = XY. if you get +A Atk, it becomes X(Y+A), which is a change of [X(Y+A)] - [XY] , which simplifies to AX. therefore, how much your range (numberically) increases from +Atk is purely based on Main Stat.

what some people got this confused with in the first few posts was relative increase (so we wouldn't be looking at the +range on weapons). it would be [X(Y+A)] / [XY], which simplifies to (Y+A)/Y or 1+(A/Y), thus relative increase in range is purely based on how much Atk you had initially

this is a simplification of the explanation given before, which took into consideration both Atk and Main Stat changes at the same time. this one assumes you don't change Main stat, which was the problem in the end in the OP's case. @duriel123 the AB shouldn't be squared

[quote=duriel123]Yep, that makes sense now, I just thought I would clear up a common misconception about the atk to stat ratio.[/quote]

That's confusing, care to put it in dummy form so I can understand? o.o

Yep, that makes sense now, I just thought I would clear up a common misconception about the atk to stat ratio.

@duriel123 that's true! My old dagger used to have 15%luk while my new dagger has boss% and higher attack as well

Max Range = k(mainstat)(total atk), where k is some arbitrary constant
Max Range after New dagger = k(mainstat+A)(Atk + B), Where A = The mainstat bonus deviation between your 2 daggers, B=Atk deviation between your 2 daggers
Range change with dagger = k(mainstat+A)(Atk + B) - k(mainstat)(total atk) = k((mainstat)(atk) +A(atk) + b(mainstat) +(AB)^2 - (mainstat)(atk))
Range change with dagger =k(A(atk)+B(mainstat) +(AB)^2)

Range change with dagger + thorns = k(A(atk+30) + B(mainstat) + (AB)^2) = k(A(atk) + b(mainstat) +(AB)^2 +30A)
Substituting previous equation,
Range change with dagger + thorns = Range increase with dagger +30Ak

The only explanation for left hand side to be greater than right hand side is if Ak is negative. Since k is obviously positive, the only explanation would be that your new weapon has gives a lower base stat boost than your new one.

EDIT: AB should not be squared, but it doesn't effect the end result.

@Wubzey, I think the ratio difference would only decrease his proportional range increase, not the actual value. The value of a range increase due to atk increase is directly proportional to his mainstat, the value of his range increase is independent of his total atk(although his proportional range increase isn't). As the mathematics suggest, the only explanation is that his mainstat somehow decreased between his new and old dagger.

@Wubzey Yup, its true... Heheh I tried with channel karma too and same thing happened...

Do you mind telling me the ratio I suppose to have?

No, its probably because you have too much atk compared to main stat so equipping your new dagger (which is adding a certain amount of attack more than your current one) gives less of a range boost with thorns than without it since thorns also adds weapon atk, decreasing the effectiveness of your new dagger. Just get more luk and you'll be fine.

[quote=oakmontowls]its changing your ratio of attack:luk making the amount of range added fluctuate. That or its just glitched[/quote]
Even if the ratio changed, the amount of damage increase from thorns can only increase, it has to be a glitch.
