How Do Item Identifiers Calculate Item Stats?

I'm wondering what the probability distribution curves look like on identified item stats.

All items are stored in Wynncraft's databases with a single stat, e.g. "10" for xpBonus.

If it is stored with a "10" for xpBonus, the identified item could have anything between 3 and 13 xpBonus.

However, is this a weighted distribution ?

 

AHHH MY THING!!!
ID RANGES

You have a base number.

You multiply the base by 0.3 (minimum) and 1.3 (maximum) to get your ID ranges.

Example:

Base ID: 10

Minimum: 10*0.3=3

Maximum: 10*1.3=13

Range: 3 to 13

For Negative ID's, you multiply the base by 0.7 (maximum) and 1.3 (minimum) to get ID ranges.

Keep the numbers positive when you do calculations, then add the negative sign after.

Example:

Base ID: 10

10*.7= 7

10*1.3= 13

Range: -13 to -7

 

If you want an even more in-depth guide than above, see this thread:

Which means that the average value of a stat is less than its base?

 

For positive id's, yes. For negative id's are they equal
