It allows you to keep the max roll (or whatever the roll was within its range) of an affix when you upgrade it to the next tier. So if the current roll of an affix was 75% of the max for the tier, when you use the glyph of order you are guaranteed a roll of 75% on the next tier up rather than a random roll.
Ok, if you have a t4 necro damage affix of 54%-68%. You got 60% (which is a 42.8% roll based on the ranges), when you use a Glyph of Order to upgrade it, it keeps the “42.8% roll based on the affix range” & applies it to the t5 necro damage range (70% - 105%) & you are guaranteed a roll of ~85% increased necrotic damage.
TBH, the example is simpler with a max roll on the t4 affix, since that max roll is preserved when the affix is upgraded.
It essentially will “copy” your roll you have on your affix and transfer it over to the next tier.
Example: I have a T4 Health Suffix with 60 health, and 60 is the maximum it can roll on that tier, upgrading it with a Glyph of order will ensure it will roll the maximum it can roll on the next tier.
So the T5 Health Suffix will be a guaranteed maximum value instead of a random value when you normally craft.
Without knowing the item type, its hard to know what happened. But you’re likely confused as to what the intent of the glyph is
Lets say you have an affix “A” with a roll range from 1-100 on an item, and that it rolled a 50
Now lets say you want to upgrade the affix to the next tier which has a roll range of 101-200.
If you use the Glyph of order, you are guaranteed to get at least a roll of 150. This is because in the previous tier your roll was at 50% of the range. Therefore, for the next tier, with a roll range of 101-200, 50% of the roll range is 150.
Without throwing in hypothetical numbers, I would answer as follows:
Hold ALT while mousing over the item you want to craft on. Look at the mod you want to improve and look at the range of values for it’s current tier. The closer it’s current value is to the maximum value within the current tier, the more worthwhile it would be to use a glyph of order.
If the affix in question has the max value for its tier, glyph of order will guarantee that when you upgrade one tier you will get the max value of the new tier.
