Any recommended places to go to for a character about to reach level 6? For the most part I've been barely scraping by with money, so I was hoping to get some for first taxes at least.
Spend all your money on IDing unknown Scrolls, Rods, Books, Potions, and Ores. When I say unknown, I mean stuff that's coming up with names like "Blurry Scroll" and "Mossy Book", or Ores that sell for only 2gp. After you've ID'd one of those once, every subsequent item of that type will come show up with the right name and can be sold for full price.
Once you've invested in IDing most of the common Scrolls, Rods, Books, Potions, and Ores, your dungeon runs will become immensely profitable.
Go to the Truce Grounds and find the altar of Yacatect of Wealth and start worshipping her. Her passive ability causes monsters to drop body parts at a MASSIVELY higher rate. After you ID a single skin, heart, eye, blood or bone, all other body parts of the same type from any monster will be able to be sold at full price (100-200 a pop for body parts coming from early monsters).
Secondly, learn the Anatomy skill to up the body part drops from monsters even further.
Yacatect + a decent Anatomy skill results in tens of thousands of gold in body parts from a single dungeon run. Pair that with Scroll/Rod/Book/Potion/Ore drops and you're raking in gold from dungeon runs.
Finally, learn the Sense Quality skill and don't spend your hard earned gold on IDing equipment.
