Is there a guide on professions and what each of them can do? I just switched to Trickster for a reason, and now I can’t remember what I was doing. There were three choices, and one of them required being a trickster, but I’m blanking. Anyone?

Tier 1, 2 and 3 professions are generally very similar, mechanically. They just give you a unique item and a weekly salary. Tier 4 professions are the same, but each one also has particular unlocks and benefits in the late game.
