Thalla the Taskmaster in is a slow-moving brute of a boss found in Paradis in the first major area, Dawnshore. There you will fight Thalla after confronting the Sparrowhawks harassing the Apothecary merchant, Grysca. You can speak with Thalla initially next to the stairs leading up to the Apothecary, but he won't fight you until after you've given the Ambassador the emperor's missive and confronted Wetenu and his goons at the shop. Thalla has a handful of heavy attacks that are relatively easy to dodge, and you'll get some decent loot after taking him down.
I was Level 7 when I took him on, and didn't have too hard of a time, so you can probably approach him between levels 5–8, depending on your skill level and difficulty settings. I wasn't expecting an encounter at first when I approached the Apothecary, but a cutscene and dialogue interaction with Wetenu will automatically trigger when you approach the shop, so prepare yourself beforehand. If you're playing a Ranger or Fighter build in , the Evasive dodge passive ability is useful for Thalla because you'll be dodging out of his attack radius often.
Thalla the Taskmaster isn't hard to find, and he didn't end up fighting me right away, so I wasn't even sure he was a boss at first. He's located on the east side of Paradis at the bottom of the stairs outside The Mermaid's Den. Fast travel to the Eastern Paradis Gate Beacon and head north up the first set of stairs, following the road straight until you see the big ogre on your right. You'll be able to speak with him to discover that the Sparrowhawks aren't going to attack you (yet), and will then be free to roam the area.
The three treasure map locations and rewards in Avowed's first area, Dawnshore, include the Intimidating Feline Codpiece and Woedica's Inheritance.
After exploring and completing various side quests, I finally decided to advance the main quest by speaking with the Ambassador and giving him the emperor's missive. Once completed, I went to stock up on
