My mentor taught me that when you are looking at the list of abilities and herb has the first one is the strongest of the list and the last is the weakest. Like if an herb is for prosperity, money, and love. You would understand that it's abilities for love is there but weaker. So if it was love you were trying to effect (ethics aside for this example) you would look for herbs with love first. Also another thing is the elemental properties.
So this time your trying to deal with someone who is causing you trouble. And its at a level that your wanting to put a stop to it. So your looking for herbs that are about protection, war, success. Well what element is best for that? You'd think fire. So you'd skip herbs for water. Because if you mix water into fire what happens.
Happy spell crafting 🕯
