Within Recipe, the Inscription subtype gets its own tracked table here. Each row below carries its own price-history page rather than sharing a single blended entry.
Pricing here moves the same way the rest of the catalog does — Retail pulls hourly from the Blizzard Auction House API, while the classic editions pull from TradeSkillMaster on their own cadences. Each snapshot is timestamped, so the detail page for any row below plots real movement over time.
The "Browse subcategories" links on the parent Recipe page list every other subtype if you want to compare markets side by side.
