Resplendent Regrade Scrolls

Resplendent Scrolls are made using a Lucky Point (Sun/Moon/Star) alongside its corresponding Regrade Scroll

Using a Resplendent Scroll will add an additional chance upon success of upgrading an item twice, resulting in, for example, a Celestial >> Epic regrade in one go.

Having a Success on any regrade using a Resplendent Scroll gives a 20% bonus chance (1 in 5) of going up an extra grade.

So for a regrade like Divine > Epic at Normal Difficulty, you have a base 10% chance of regrading to Epic. Should your regrade succeed, you then have a 20% chance of going Legendary. This gives a 2% great success chance (10% * 20%)
