Making gold
Several things:
-gather everything you come across while wandering around the world & salvage anything that’s level <65ish. Sell what you get.
-world bosses are a decent starting point to make some money. Here’s a timer, do them, salvage the rares you get and then sell the globs of ectoplasm on the TP.
-if you have a level 80 character, dungeons are a reliable way to make gold. Gear yourself in rares or exotics if possible, then run them. If it’s your first time running them, make your own group via LFG and say something like “p1 first timer” so you can 1. avoid speedrunners who would get annoyed at you, 2. be able to run with either other newbies so you can figure things out yourselves or have an experienced player drop in to help. For starting I’d recommend Citadel of Flame path 1, Sorrow’s Embrace part 1 and Ascalonian Catacombs paths 1 and 3, possible Crucible of Eternity path 1.
