Modifications are the gem-costing actions when you select an item equipped on a hunter.

The best time to modify is during the modification event (Wednesday & Sunday) to reduce the cost by 10 gems per modification.
MODIFY QUALITY: Changes quality from anywhere between Poor to Ultimate (even Poor to Poor).
MODIFY ATTRIBUTE: Changes the % values on the equipment. For example, if I modify attribute on the left item, my +ATK 18% could change to a +ATK 10%.
When you modify, the costs increase; and there’s an unlimited amount of times to modify. See the table below for how it increases.
Modification Attempt | Gem Cost |
---|---|
1 | 40 |
2 | 40 |
3 | 40 |
4 | 70 |
5 | 70 |
6 | 70 |
7 or more | 100 (capped) |
