Nobody in Terminus buys goods; they buy a position. You were raised on the trade floor, watching the rolling hour-by-hour auction of everything riding in off the Asylum, learning to snipe an anonymous lot before it cleared and to ramp your own stock to fleece a rival. Every fortune on that floor lives in the gap between what a thing cost the day it shipped and what it's worth the day it lands, and you have lived in that gap your whole life.
Choose one of the following skill boons.
A handheld auction terminal with a half-dead screen that still pulls live prices a beat before the public feed. Held together with tape and larceny.
Once per session you can read or ride a price swing on the spot board, calling roughly which way a lot will clear. You may reroll a failed haggling or Marketeering check.
You price everything on sight, including your friends.
You cannot walk past an auction without stopping to watch it clear.
