The 6th Pentacle of Mars

From the Key of Solomon. The 6th Pentacle of Mars renders the bearer invulnerable. The manuscript tradition states that enemy weapons turn against their wielders. This is the most aggressive defensive pentacle in the entire Key of Solomon. Whatever your adversary throws at you comes back at them. Your pentacle will be handcrafted in metal and consecrated in the day and hour of Mars according to the Solomonic tradition.
