GOP upgrade factors

So I melted a bow that had 4.6M glyphs in it to upgrade another bow. After upgrading the second bow to the same level, I still had 1.2M glyphs left. I was surprised so double checked the level and GOP balance. All was correct, it had cost 1.2M glyphs less to upgrade the second bow.

What are the factors that go into determining upgrade cost? I know level, # of upgrades, type of item are all important. But do the enchantment lines factor in? Do certain enchantments cost more to upgrade than others? Best I can tell the new bow was cheaper because all the enchantments were % lines.

 

In my experience the % lines make it more expensive to upgrade now. My sw's wand with 3x speed and 1x weapon damage % lines costs 80 mil to upgrade from 45 to 50. While his staff with 2x damage and 2x weapon damage % costs only 41 mil for the same lvl upgrade.

 

Well that's frustrating, seems to be the opposite of what i'm seeing. Maybe yours is not the enchant lines but difference between a one and a two hander.

 

That may be the case. But I find it a little odd that the % lines differ by half and so does the upgrade cost.

 

Here's my theory.
I've been asking myself a lot, what does determine the gold value of items?
Before the R139, I already noticed that identified green items (base gold value of around 10 silver) with higher crit damage lines would add up to 30 silver to its value, so their total value would be 40 silver. Green items with lower CD lines would only add a few silver, so their total value would be only 13 silver. This was only the case with green items with CD lines, other lines didnt affect the value at all.
After R139 the same system was applied, but with every %line, so att speed, CD, %Block etc. However, i didnt see the same happening with blue purple and orange items.

Now it happens to be that i'm still hoping to find that one perfect 2H sword and for that i need a lot of gold. At the same time i need a lot of GoP as well, so now i had to choose. This made me look closer to the purple items i farm in m2 and this is what i found:
Observation 1. Some purple items are worth only 99 silver, while others are worth up to 1.59 gold, however, the GoP value is still the same.
Observation 2: Items with higher value lines have higher gold values. For example, armor values can be between 134 and 268 (for a dk). HP values can be between 184 and 322. So a torso with 134 armor, 140 armor and 190 hp is worth around 1 gold, while a torso with 268 armor, 250 armor and 300 hp is worth around 1.5 gold. This is an example of lowest vs highest values, but of course there's everything in between. One low line and 2 high lines could result in a value of around 1,45 gold.
Observation 3: For as far as i have found this system applies to every type of enchantment. However, it seems like even low damage values on any item except weapon or weapon adornment, adds a lot to the gold value.

Now i think something similar is applied to upgrading items and their GoP cost. Let's take the torso again. Where upgrading the low value torso costs maybe around 1M glyphs, upgrading the high value torso may cost up to 3M, maybe 5M.
With weapons the same system is applied, but of course upgrading weapons is more expenxive then upgrading other items.

Why is the gold story important to my need of gold and glyphs you may ask. Well, knowing what i know, i sell every purple item which is worth more then 1.4 gold and i melt every purple item which is worth less the 1.4 gold.

 

definitely not. You can easly check this by upgrading EO items. Each item of the same sort costs the same GoP independant from the gold value

 

I think the better the item the more it cost to upgrade. If the %s are high the cost to upgrade goes up. I have not done a lot of research but I can.

What I suspect.
Speed and critical damage % raise the price. Once over 5% speed below 10% is one price 10 to 20% is another.

Critical damage% 9,9 and below is one cost 10 to 30% is another 30,1 up is another.

I made this picture and it seems the diff from white to green is 5x so will check if green to blue if it is 5x per mode higher or what.

5x is a rough figure it is almost 200 GoP differenace.

 

hmmm, strange strange strange. I never see difference in my EO.

But in your img the 1° green costs less to upgrade then the white item

 

I m not saying there s a correlation between upgrade cost and gold value. Im just saying that i think that the correlation between enchantment quality and gold value, might be similar to the correlation between enchantment quality and upgrade costs. I havent figured it out completely though.

 

I have figured it out. Here are my findings.

If you have an item that is all % and has a base armor that upgrades only. The cost to upgrade 1 time is high and the exact same cost as if you take the next lowest item same quality and upgrade it to that level.

I had a blue crystal level 16 with 2x % the one time price was the exact same as the level 13 no % blue upgrade to 17. Each where the same from then on.

 

Hi, here's my theory, based on observations of a large number of items :

First, what we know :
- enchantments and "hardware" are upgraded separately : you can check it when you first upgrade a level 45 item to level 46 : it costs more because its enchantements are only level 43 and need to be upgraded by 3 levels.
- base item level counts too : the glyph cost for upgrading a level 7 item from 46 to 47 is 10 times more than the cost for upgrading a level 45 item from 46 to 47
- upgradable enchantments are split into 6-level tiers with different value ranges : 7-12, 13-18, 19-24, 25-30, 31-36, 37-42 and 43+
- non upgradable enchantments (percent values) have the same value ranges for all levels (except for the "super high" values that can be found on level 43+ legendary items)

Now, what I think happens when you upgrade an item with ONLY NON-UPGRADABLE enchantments : the game determines the base levels of the item and of its enchantments. For the item, it's easy. For the enchantments, it takes the maximum level of all present enchantments. But for those special items, this gives an enchantments' base level of 7, because there are no tiers. So it applies the normal upgrading cost for "hardware" part, but applies a x10 factor for the enchantments part, because they seem to be "level 7".

EDIT : Just forgot to write the conclusion : this is a bug.

 

I only find that amount of GoP is in line with amount of stats upgrade. On one of my characters upgrade leg bow from lvl17 to lvl18 was 63k GoP and it give me +5dmg and rest... upgrade from lvl18 to lvl19 was just 35k GoP since stats are little less upgraded (+2dmg and rest...).

 

That's because the enchantments on your bow are only level 13, and need to be upgraded by 5 levels when you upgrade it to level 18. Because of this, most of the time, the first upgrade for an item costs more than the second.
