You may have already come across her during your Wolcen's adventures, the Fate-Adjucatrix Zeitgeist merchant is marked on the map with a coin purse, similar to the sellers in town. It can be encountered in almost all game modes and maps — and this is an opportunity not to be missed. In addition to the fact that she can buy your useless items — which is a luxury on high-level expeditions during which the return to the city is impossible — she also sells a wide selection of items.
Her first tab is usually overflowing with rare items, and there are sometimes legendary items — even if they're exceptionally rare. What interests us are the following tabs.
Her third tab always offers two random unique items that have their own appearance and their own statistics of a fixed type — but not their values. Beware, unique items are generally interesting for a very specific gameplay, in which you have to design a build around these items to exploit their special power — reminding that of the legendary items in Diablo 3 for example. This means that they can be useless or even harmful to your character.
Even if they still deserve your consideration, don't feel pressured to buy them. They're sold for a small fortune, between 10,000 and 50,000 gold coins on average, depending on the level of the item. That's way too much knowing that gold becomes precious at the end of the game.
Finally, her last tab sells high level gems against Primordial Essence, which is a good deal on a high level, but we advise you not to waste it — Primordial Essence is precious to rebuild the city once the campaign finished.
The issue now is how to find this famous seller, and unfortunately we don't have a miracle solution for the moment... We can simply advise you to watch the map and all its corners. Some techniques such as the Aether Jump and the Roll allow you to move very quickly without having to kill any monster — it's a good way to look for her. We've also come across her occasionally in the optional mini dungeons, even if it wasn't very frequent.
