  • Crafting quality chance

    Hello.

    How crafting quality calculated ? I can't find the formula.

    What is my % to craft X quality item of tier Y when I have Z "crafting quality" ? Anything else should be taken into account ? (I take Z as skills+food).

    Thanks.

    Y is irrelevant

    assuming Z=0% then 1 roll determine your item quality , probability of each quality level is :

    quality : %
    +100 : 0.001
    +50 : 0.011
    +20 : 0.05
    +10 : 0.25
    +0 : 0.688

    assuming Z=100% , that means 2 rolls determines your item quality , then probability of each quality level become the probability of the best of 2 rolls...

    quality : %
    +100 : 0.001999
    +50 : 0,021857
    +20 : 0.0963
    +10 : 0.4065
    +0 : 0.473344

    Now assuming Z=10% means your "2 roll" frequence when crafting is 10% : and then your global chance is ...

    quality : %
    +100 : 0.0010999
    +50 : 0.0120857
    +20 : 0.05463
    +10 : 0.26565
    +0 : 0.6665344



    I think Z=10% when by destiny boards you get 100 "increase in quality while crafting an item" , but I'm not sure .

  • Hey there,

    here is how it works:

    Without any quality bonus, you get 1 roll on the quality table.

    With a crafting quality bonus of X%, you get 1 roll on the table, but have an X% chance to get a second one.

    If your crafting quality bonus is above 100%, say 150%, you get 2 rolls on the table, and a 50% chance for a second one.

    Now, when you have multiple roles, only the best one counts.

    In short: 100% crafting quality bonus means that you get 1 free reroll on each craft.

    With regards to the actual table:

    Quality Level / Chance
    4 - 0.1%
    3 - 1.1%
    2 - 5%
    1 - 25%
    0 - 68.8%

    With regards to the actual table, I do not have access to it right now, but key probabilities roughly are:

    ~0.1% chance to get the highest quality
    ~1% chance to get the 2nd highest quality
    ~5% chance to get the 3rd highest quality.

    Will look up the exact numbers and report back.
    If those numbers are correct, why does anyone craft when they can auto upgrade quality via the repair dude? XD

    Whats the reroll chance with maxed masteries in a craft tree?

  • I've got somewhat of an approximation, but as a graphic (based on 4 big samples on quality-increases of 0, 480, 730 and 920)


    Basically, when almost maxed, you craft <2% normal, 50% good, around 37% outstanding, 10% excellent and 1% masterpiece.
    Base-chance on Masterpiece is 0,1% and on excellent 1%....so - you *10 those chances with high masteries

    Good to know the actual mechanic, though - maybe I'll math it a bit more precise now.

    @Korn
    Now, still got a question:
    How is focus and food handled?
    Is food the flat +100 quality (aka +1 re-roll).
    And for focus, is it +50 quality, +50% increase in existing quality, or something different?

    Is there a cap on highest quality(aka amount of re-rolls) - e.g. if you're 100/100/100/100, then focus or food won't matter?

    Is there an experienced high skilled crafter here to confim theorical maths above (by @ZaZii and @Gwanaelle) ?

    for example, with 1000 increase quality , can you confirm you get less than 2% normal .
    or, with 500 increase quality , can you confirm you get 10% normal
    I said, I did it based on samples. 920 is pretty close to 1000 increase and thats what I had, 2% norm chance.
    similar with other


    Edit:
    my sample was like 2000+ items/each on those 3 quality-stages.

  • Then all this is nothing more than crap.

    Having all 4 (5) masteries maxed to 100 and your chance for Masterpiece isn't worth it. Only focus reduction would matter.

    Following this it's not worth to push all 4 (5) masteries to 100 in one branch. Better to open few item types.

    Cheers,

    Focus is a function of item value and focus efficiency:

    BaseFocus=(1.75^LOG(ItemValue, 2))*10

    FocusUsed=BaseFocus*(0.5^(FocusEfficiency/100))

    BaseFocus formula is for 1 resource worth of craft, so you need to multiply by how many resources is used for item.
    (eg 2h weapon uses 32 resources, so multiply by 32)

    LOG(ItemValue, 2) is syntax for google sheets, it means log2(ItemValue)

    I know how focus-costs are calculated... I meant the quality-increase from focus^^
