Start by locating the vendor data for NPC ID 14847, Professor Thaddeus Paleo, and inspect how the listed item entries are made available. Compare the vendor's current stock with the requested level brackets and pre-patch availability notes. Done means restricted scrolls and potions appear only in their intended progression brackets while unrestricted items remain available.
