Finishing reagents raise crafting quality in Retail’s work-order system, so demand follows the crafted-gear meta tier by tier. Finishing Reagents — one of the subtypes World of Warcraft files under Tradeskill — gets this table as a focused view: the same drill-down the in-game Auction House browser applies when you filter by subcategory.
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 Tradeskill page list every other subtype if you want to compare markets side by side.
