What would Catholics have in a religious bug out or EDC kit if the event that the three days of darkness actually becomes real?

**What would Catholics have in a religious bug out kit in their homes if the events that the three days of darkness actually becomes real, as expressed by several Catholic mystics?** I am very much into the Great Outdoors, so I always have an [EDC kit](https://en.m.wikipedia.org/wiki/Everyday_carry) with me when I am out camping or hiking in the wilderness. This has inspired me to ask this question here as a sort of Catholic EDC kit for those Catholics that are more traditional minded or even very Marian minded Catholics. Catholic Stigmatists and Mystics like Blessed Anna Maria Taigi (1769—1837) have spoken about the three days of darks that will befall mankind as something that will inevitably happen to the human race. What do Catholic saints, mystics and stigmatists recommend that the faithful keep on hand in their homes in the event that the three days of darkness actually becomes a reality. Any other things that the faithful must do in order to remain as safe as possible during these days are also welcome.
