Let us improve the aspect range of uniques somehow.
Having very good or max aspect stat makes or breaks a unique.
The range for example on a tal rashas ring is from 40 to 80 in steps of 2.
If you finally find one with the right or more than one greater affix it is a huge bummer if it would roll only with the aspect of 40.
To make the item still usable and to improve it i like to suggest a craftsystem to improve it.
Let us combine a unique item with unique items of the same type. Each time 2 uniques get combined the aspect gets changed to the next step. The second item gets sacrificed to improve the aspect stat from the first, while we keep the first item. So from 40 to 42. Maybe with additonal fees or expenses like mats aswell. Maybe even with increasing costs for each improving.
So to improve it to max i would need to sacrifice 20x times the same unique in thid case i woulf need 20 more tal rasha rings to improve my main tal rasha ring.
This system would improves the ability to get items without trading and incents to collect more uniques of the same type.
Make farming great again.
