Binding spells are a unique form of magic. Unlike many of the other defensive techniques, binding spells do not remove or solve any spiritual problem. They are a type of protective magic but, unlike warding, the focus is not on protecting you from harm but rather on preventing the harm from happening in the first place.
They’re a fairly gentle method, but can be quite effective on even rather serious problems such as being intentionally cursed. The intention of a binding spell is always to prevent your adversary from taking some action again. Whether it’s to stop someone from casting the evil eye upon you, to stop another person gossiping, or to prevent another witch from casting spells on you, you go straight to the source of the problem.
Binding spells do have two major flaws. Since they’re a spell cast on another person, that person can break the spell if they realize it’s been placed on them. This makes doubling up with a binding spell and a ward a good idea if you’re binding a witch. The other big flaw is that they tend to be pretty specific. You have to know who you’re binding and what you’re binding them from. While you can bind someone from generally causing harm these spells are more effective if you get specific. What this means is that if you don’t know the source of the problem, you can’t bind it. You also might bind them from taking one action only to have them lash out at you another way.
This is not to say that this isn’t an effective problem-solving tool! It is, but you must always know the limitations of your tools so that you can make the best choices about how to handle your individual problem.
