Hi. I've been role-playing an "anti-theist" character who acknowledges the existence of the gods within the fiction, but refuses to worship them, request their aid, or otherwise interact with them in a cooperative manner. As such, my character has never taken any action which might be interpreted as religious.
However, despite this, on my longer-lived playthrough attempts, where I get to level 10 or so before dying (I'm new to the game, so I don't get farther than this, at present), the death screen says of my character, "He was religious. He did not ask for divine assistance." Only on my characters which die at extremely low levels (e.g. 5) does the game say "he was not particularly religious."
What is causing the game to inaccurately assess my character as religious? I've never used (or even found) holy water, I've never used an altar (on two of my "he was religious" games, I never even found an altar), and I didn't ask the healer for either instruction or healing. I've done lots of searching on this site & the wiki, and the latter says that reading certain texts is interpreted by the game as a religious action; however, my characters have mostly been too illiterate to identify any of the scrolls I've found, and I've never been able to identify the books.
So, what is it that my character is doing that might cause the game to register a "religious" action? Is it killing zombies? Attacking chaos NPCs? Simply refraining from chaotic acts?
