The AI has rotted your brain man. Tracking arrows, what this entire post is about, doesn't need a fucking LLM. It needs tally marks on a sheet of paper, at most.

Use More Purple More Better's editable PDF player sheet templates. You can load in sourcebook data from external sources easily and have everything from every sourcebook at your fingertips. And you can still enter custom shit like custom magical items easily.
