Im aware that this is a concern to people directly and indirectly involved (and in honesty a partial reason for this guide) with someone doing stuff frowned upon the community in the trade markets. But pls don't bring up this problem in this thread, thx :)

Looking for Set items! Msg me id costs and the level :)

Due to some controversy in the past about selling unided items, Id like to clear a few things up about IDing cost and how you can (partially) know what it will be before you ID it.
(If this violates any rules, pls let me know)

Basic Mathematical Knowledge

Now I hope you're familiar with basic graph theory which IDing cost is based on. The cost for iding stuff varies with its tier (unique, set, rare, legendary, mythic) so every tier has their own function.

The cost has 2 parameters, the 1st one being the constant cost that all items in its tier have and the variable cost that is dependent from its level (of the item).

The viewable cost is the cost you see when you first id it (from unided to ided, or pre-gameplay update id to id). Every sequential roll (called a reroll) will cost you 5 times the amount. A rereroll 25 times.
The constant cost is the base where technically the cost is for a level 0 item.
The dependant cost is dependant of the level. Multiply it by the level.

Range of f.e. 96 to 92 will contain levels of 96, 95, 94, 93 but no 92.
This would belong to the range of 92 to 88.

You can of course calculate this the other way around as shown in the second equation.

If you get any fractions of this equation for cost (NOT FOR LEVELS), round upwards!
Example: 141.3 turns into 142.

If you get any fraction of this equation for level (NOT FOR COST), round downwards!
Example: 83.7 tunrs into 83.

And finally: The method used for rare and unique items was a linear regression.

Unique

Remark: Some costs are identical so there is an uncertainity of -1 Level!

Set

Rare

Legendary

Mythic

I hope this clears things up for most people. I made a list of all mythic costs below (spoiler).

Mathematical Example

You've got a unidentified legendary chestplate around level 92 to 96.
You check the cost of iding it which is 600 emeralds.
You use the parameters for legendary items c = 30, m = 6.

You'll go check on wynnapps.com what that could be: It is undoubtly Aquarius.

Let's do another one, a bit harder. You got an unidentified unique bracelet around level 80 to 84.
You check the cost of iding it which is 45 emeralds.
You use the parameters for legendary items c = 3, m = 0.5.

View attachment 111373

You'll go check on wynnapps.com what that could be: There is none.
You apply the uncertainity of -1 level. Now it is level 83. It is undoubtly Squid Anklet.

Flaws to this method

This method cannot differentiate between 2 items that have the same level and the same tier.
Such an example is the mythic wand Fatal and the mythic wand Warp. Both are level 99.

Unique and Rare items can have an uncertainity of -1 level.

Disclaimer: Thx mr_wolfgang (is a newbie, might not have forums) for helping me with low level uniques!

Similar guide does exist. Credit to @DerVillager here

Im Still looking for some set items. If you have any (even lower level)
pls tell me what item it is and its cost of id or reid

Updated set items, thx Lord_He1mchen and Someone (socantab) for the data!

basically the 32 bit integer java limit is
2,147,483,647
emeralds
and even if you reroll past that limit (through the power of doubt normal rerolling)
it will never get past this number

So, almost 8.2k stacks of LE.
Ya, I think we good lol.

Awesome guide mate!

ID costs have been updated. The calculation were run by @dukioooo and is now updated and available on wynndata.tk .

Empirical Changelog:

In short:

IDing uniques now costs more.

IDing sets now costs more.

IDing rares costs more up to level 24. Starting with level 26 the cost will be, in theory, less.

IDing legendaries costs more up to level 12. Starting with level 13 the cost will be, in theory, less.

IDing mythics has not changed.

Yes very basic mathematics, I knew this very well. I could solve that in my sleep
