If you start running low on Scrolls of Identification (commonly called ID scrolls) you can always buy more from the Wondrous Bazaar using Astral Diamonds. To easily access the Bazaar, press the Alt key on your keyboard then click the fourth icon from the left on the toolbar at the top of your screen (it’s shaped like a Diamond).
Click the 1. Store option and you’ll be taken to the Wondrous Bazaar shop. Here you can choose what level of scroll you need. There are three different versions of Identification Scrolls:
Lesser Scroll of Identification can identify items up to Level 29. (15 Astral Diamonds)
Scrolls of Identification can identify items up to Level 59. (45 Astral Diamonds)
Greater Scrolls of Identification can identify items that are Level 60. (125 Astral Diamonds)
