I'm playing Dark Mode for the first time and I'm trying to get the Blasphemer's outfit early on.

Unfortunately I'm poor and I don't really know any other methods to get money besides arm wrestling in the inn (which only nets me 30 orens per win).

Go out into the forest and grind some Endregas and Nekkers and sell the alchemy ingredients. Kill everything that spawns in the day, go back to flotsam and meditate till midnight, then go back to the forest and kill everything again. Rinse and repeat. Be careful not to sell the Warrior Nekker's Blood (quest item you need later on) or Endrega Embryos (one of your only sources of Fulger in Chapter 1).
