Quick idea I had and need to note down before I forget it:
a witch bottle designed not to harm the incoming energies (like most witch bottles seem to be with their nails, thorns and black pepper) or block them (like the protective witch bottles I’ve seen with rosemary and basil), but filter and transmute.
Somebody throwing bad luck at you? Great, you’re giving me energy, I’ll filter it and change it into a blessing.
“When life gives you lemons” sort of idea, inspired by a post I’ve seen floating around about that witches shouldn’t ground bad energy, but filter it and transmute it, because earth only can take as much negative.
