Silver Trader location and unlocks
The Silver Trader is in a house in Svartrau City/Altenmarkt, west of the Cathedral complex, marked by a white goblet. Two unlock routes are reported: complete Into the Den and loot the marked cache, or reach Infamy level 4 (Notorious).
The trader accepts silver rather than ordinary currency and sells high-quality weapons, armour, accessories, and consumables. Selling 1,000 denarii unlocks the Smuggler objective. Published examples include The Shredder, Slasher's Pendant, Artisan's Tunic, and Potent Powder of Sharp Mind; the purse is finite.
Exact stock and prices must be checked against the current retail build before being labelled complete.
