How can I make a game of D&D5e playable in a Sabbath-observing environment?
Being a person with some semblance of a real life, and the same applying to my players, I often find myself in the position of only having several hours of free time on Saturday - Shabbat (the Sabbath), a day where, as a religious Jew, we traditionally refrain from anything considered "work", including writing.
For RPGs, particularly D&D5e - which is the system we're using - this poses a problem. I as the DM often find myself making notes either on paper or electronically, and the players use pencils to mark HP, spell slots, etc. on their character sheets, as well as taking notes, marking down inventory items, or solving puzzles that I give to them.
Essentially, I need to find a way to run a game without relying on writing at all, from either the players or the DM.
How can I make a game of D&D5e more easily playable in a Shabbat-observant environment on Shabbat? I'd prefer answers that avoid potentially expensive items such as a HP counter ring, although I'm aware of the potential that those might be the best approach to take.
