Every tradeable Tomb of Amascut unique, indexed to its price at the start of the window.
ToA's uniques only enter the game through raid completions, and the raid's invocation system means the effective drop rate per team varies with how hard players choose to run it — a shift in the community's average raid level can move supply even with no change to the game itself. Tumeken's shadow trades uncharged; the Masori pieces trade in their flawed "(f)" state, which is what the raid actually drops.
Every line is indexed to its own price at the start of the selected window rather than plotted in raw GP, so a Tumeken's shadow and a Masori chaps piece stay comparably visible on the same chart despite being tens of millions apart in price.
