Tarlaro is a young, silver-haired woman described as an "arcanist" or "elementalist", who seems to be skilled in making elixirs. She is located on the village of Durnsig Tarlaro sells some powerful elixirs in exchange for AT but their value severely diminished after a massive price increase in 2014, they now cost three times as much as they did originnally. She doesn't always have elixirs for sale, but when she has, it is reported on your Adventure Finder as an "available event/scenario" but only if you're able to purchase an elixir from her.
