How do you block magic?

In order to block magic, you would need to be pro-active and protect yourself/loved ones/home from any harmful influences. Witches Bottles were commonly used for this, an ancient defence, known throughout folklore. It is made on an individual basis. The idea is to protect yourself and at the same time, send back whatever is being sent at you. You should never be the originator of harm, nor seek revenge, but you can protect yourself. To make a Witch's Bottle, take a bottle or a jar. Half fill it with sharp objects, also add herbs and crystals of protection. It should then be buried where it can remain undisturbed. So long as the bottle remains buried and unbroken, it will protect you from any evil directed against you. Other forms of protection include Amulets and Talismans. Talismans are active objects designed to give specific power, protection and encouragement to those that wear or own them. Amulets are intended for general purposes and usually provide reactive protection from danger, illness and ill-fortune.
