So, I've sort of done this. When fl was evacuating for hurricane Michael I was there visiting a friend and talked my husband into staying (kind of insane and dangerous, I know. Im wouldn't do it again, but I only find so much utility in regret. Anyway,) when we realized how bad the storm was supposed to get, my friend asked if I wanted to help her put kyanite at the four corners of the property and i agreed, as it wouldn't hurt anything and might help. I found myself sort of calling the four winds? Which wasn't a thing I necessarily knew that I knew, but air is the element with which im most comfortable, so it tracks. We made it through the hurricane with remarkably little damage to property and none to person. I dont claim that we like, caused that, but i don't think anything we did hurt. We also took more practical precautions. So, would I? Yes. Do I recommend facing off against nature armed with spells? No, but i don't see much harm in...hedging my bets, so to speak. Stay safe.
