You can even get an item in Elden Ring called the Twiggy Cracked Tear about a third of the way through that lets your Physick flask grant the same effects as a Sacrificial Twig for 3 minutes. Once you get that, the stress of losing Runes can be greatly diminished.
Simply drink it prior to crossing a fog wall or at a difficult point on the path to Rune retrieval.
If that's not enough, and you're on PC, you can download a simple mod off Nexus which eliminates Rune loss on death entirely.
School marshalls? What on earth is going on over there in the US? Why is it the rest of developed nations aren't having this shooting issue, yet your children over your side of the pond have to learn how to take cover (sometimes in a crowd so others get hit instead) and run in a zig-zag. Sounds like a bleeding nightmare warzone.
