Crafting Skill Theory

PLEASE READ "DURABILITY ON CRAFTED ITEMS" THREAD FIRST OR THIS MAY MAKE LITTLE SENSE

If you read the above thread, you'll know I've (hopefully) discovered a formula for predicting durability on crafted weapons and armour. I believe it can be expanded to work out the "Actual skill" requirement for unknown new items. In order to do this, you need someone who can craft the item and to know their exact crafting skill, and the normal durability of the item concerned. Here's a practical example. I know that I can craft a Blood Bow, but do not know the exact skill requirement. As far as I recollect, we were told by the Soma staff that the Actual skill required is "over 50 but less than 60". So I craft a Blood Bow and get 1425 dur. The normal dur is 1200. Carry out the following steps to discover the skill requirement, where "A" will be the % of dur above norm, "B" the adjusted Actual skill, and "C" the adjusted Required skill :-

1) 1425 - 1200 = 225

2) (225/1200) x 100 = 18.75 % (Figure "A")

3) "A" = (Actual skill x 0.75 ((Figure "B")) - (Req skill x 0.75 ((Figure "C"))

4) So :- "A" = "B" - "C"
Equation rules let us also say that "C" = "B" - "A"

5) We know that "A" = 18.75 and that "B" = 60 (80 X 0.75), so "C" = 60 - 18.75 which is 41.25

6) Finally, we need to multiply "C" (41.25) by the inverse of 0.75 (which is 1.3 recurring, the same as making 3/4 into 4/3 in fraction terms), so :-

41.25 x 1.3333 = 54.9999

7) Rounding this up, we can say that the Actual skill required to craft a Blood Bow is 55.

Now I know this a bit long winded, and I hope I've made it clear. Storm and I tried the theory with him crafting Shaman Shoes, and it came out thus, where "?" is the Required skill :-

1136 - 800 = 336

(336/800) x 100 = 42%

42 = (74 x 0.75) - (? x 0.75)

42 = 55.5 - (? x 0.75)

55.5 - 42 = 13.5

13.5 x 1.3333 = 17.999

? = 17.999 rounded up to 18

All our crafting notes and website info confirm 18 to be the skill requirement for Shaman Shoes.

What I need now is some feedback. I need crafters to post their actual skill, item crafted, and dur obtained. Then, we can shove the info into the equations and see if the theory holds up. Item can be as common place as you like, but must be weps or armour. I'd also like to know if anyone understood what the fek I'm on about with the above equations

this only bit u lost me on m8, how u work out that 0.75 inverse is 1.3?

4/3 of 0.75 = 1

dont get where the .3 comes from.

I may have expressed this clumsily, I meant rather that you need to invert the 3/4 to read 4/3. Therefore, you have 1.3 recurring rather than 0.75. I used the word "inverse" in an archaic sense (i.e. to turn upside down), rather than a mathematical one which was a bit daft under the circumstances

[skullo]

the only way i see this working out properly is if itis

4/3 of 1 = 1.3 to 1 decimal place

the way i persived it was that it was 4/3 of 0.75.

so is it 4/3 of 1 not 4/3 of 0.75?

Yes, that's it m8, so it's 1 and 1/3 rather than 3/4, 4/3 of one rather than 4/3 of 0.75.

So far, the only problem items fitting into the theory are Silver Bows and Gold Helms. The formula suggests 35 Actual skill for crafting Silver Bows, yet Storm and I are of the opinion that you need 38 skill. Certainly, this was when it worked for us. As for Gold Helms, we are unsure of the standard durability. Nothing I've tried so far with these fits properly into the theory

gold helms i do belive dropped only have 600 dura??

Lol well 600 dur would totally shag the theory. It may well be that the Vod ones have that sort of dur, but differ in some way from "standard" Gold Helms by virtue of -tag or some other factor.

i know this just going over what u done bar m8 but i found it easier to brake it down into serveral equations.

1st Equation

A=crafted wep dura
B=norm wep dura
C= dura diff(Fig 1)
A - B = C

2nd Equation

A=Wep Dura Diff (Fig 1)
B=Norm Wep Dura
C=% increase of dura



A/B x 100 = C% (C% become Fig A)

3rd Equation

A= Fig A
B= Actual Skill
C=Req Skill(Fig B)

C(Fig B)=(B x 0.75) - A

4th Equation

A= Fig B
B= 1.33
C= Skill level to craft

A x B = C

C must then be rounded up to the nearest whole number.

NOTE:

i tried to simplify the procedure m8 but i couldnt find a way apart form simplifying the terms you used.
i will try the silver bow see if i can get thet to work but i only got 10.9 armour craft so i well off tezstin the gold helm.

hope the hlps ne way

[skullo]

tested silver bow and req skill came out as 35 m8.


and as far as i know it ment to be 38. Only thing i can think of is that soma adjusted the skill reqs to balance the crafting table.

where silver bows uncraftable at any stage?

if so this may explain why it dosent fit into the patern.

staff added the bow to crafting list at later date and didnt use same rule to determine the skill reqs.
