What is the use of the religion and nature skill in the game?

I am a bit of a noob, so it would be nice to know, so I can start adding some points in either on my inqusitor run.

It's a lore skill, so it's used in general lore checks in the world. For example looking at a tapestry or altar, your character will know what religion/culture it comes from and give additional information. It's also occasionally used in dialog to the same effect.

The second function of the lore skills is for identifying enemies and giving you more information about their stats. So for Lore: Religion you'll have a chance to get additional information about Undead and Outsiders and other enemies that pertain to religious themes.

The other lore skills serve similar purposes for different enemies, so it's generally good to have a person in your party who is good at each one.

Thank you for the info. Thb I am soloing atm, because I didn´t like any of the characters I met lol. I have basically just started, so we shall see how much I can solo with my monster tactician, but so far so good.

Nature skill is also for hunting when camping outside.

Nature skill is important when hunting on the map, the higher the skill, less time spent hunting for rations. In Act 2, there is a missable ranger companion with good nature's skill and with him in the hunter role, he needs less rations

Yeah, what folks said. I'd just add that Lore: Nature is definitely a pretty important skill early on especially. It is for hunting, skinning defeated animals (worth $), and for a decent number of other checks in the early game. And it's a skill not super strong in any your early companions.

Lore: Religion is probably one of the least needed skills I would say. I really only have it in a few companions I don't use much, so if you have spare skill points for this build you have and decently high WIS, it might be a good move. It kind of it helps if you are building on what your main character's strong abilities are. But in general Perception, Trickery, and Persuasion are most important.
