The catalog taxonomy files Vantus Runes under Consumable. Everything listed below shares that subclass, which makes this a focused market view rather than the whole Consumable shelf.
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.
If you want the full Consumable category rather than only Vantus Runes, the breadcrumb above steps back up one level; otherwise the table below covers every tracked item in this subclass.
