If you are going to play it, a few random tips that will make it far easier.
First, get the Animal Trophies survival skill to level 3 ASAP. This skill massively increases both the value and quantity of drops for all non-human enemies. At rank 3 it becomes your main source of income for the entire game.
Second, you can effectively buy skill and attribute points. You will need alchemy and a workbench. You buy Natural Elex and other materials at certain merchants who restock their goods every time you talk to them and craft elex potions that grant you the points. There are restocking elex vendors in The Fort and in the Camp in the Center (you have to upgrade that one).
Third, Flamethrowers are fucking broken. The standard "fireball" attack mode is effectively equivalent to a missile launcher. It fires a medium-speed projectile in a straight line as far as you can see. That projectile explodes when it reaches its destination, doing damage, setting on fire, and KNOCKING DOWN enemies. This attack can be spammed and only requires one ammo (fuel). Larger enemies are only staggered instead of knocked down, but can still be stunlocked by spamming them. Fuel is the cheapest ammo in the game at 1 elexit per unit. The only downside is you can't move much with the weapon drawn (heavy weapon walk only). Flamethrower fuel can only be bought from the Clerics.
That doesn't mean you have to join the clerics. You can still buy fuel (in smaller quantities per purchase) if you join a different faction, and cleric abilities are kind of questionable. Personally I like the Berserkers simply because they have a Healing spell and a trade-health-for-mana spell, which I can alternate both of and avoid ever needing potions.
