There are plenty of Path of Exile 2 tips that I wished I'd known before starting my Mercenary on his path of darkness and destruction because, honestly, this is a very complicated game. If you're a veteran of the original, many of the returning mechanics will make much more sense—though there's plenty that's changed—but if you're stepping into the series for the first time, there's quite a lot to learn.
Whether it's understanding stats, skills, and modifiers, or just realising that actually you can do whatever the hell you want with the game's positively gigantic skill tree, you'll have quite a bit to wrap your head around. If you want a little guidance in your fledgling hours of Path of Exile 2, these pointers should help you get going.
