You can use X star enhancement stars at any time as long as you don't have X or more stars already. So, you can use a 5 star enhancement as long as the item only has 1, 2, 3, or 4 stars, but of course, fewer stars will be added depending on how many you already have (because the scroll only takes it up to 5, you know). You should definitely use 5 star enhancements on Superior equips, it's much better than using 5 AEEs, because of the price of Superior Shielding Wards, unless of course it takes you more than 5, then it'll be a waste.
