Faerie creatures have been meddling in the lives of mortals since before recorded history, and humans have been developing and passing on ways to deal with this almost as long. This protective charm centers on knotting red threads in one’s hair, and offers some defense against the malevolent enchantments of the fae. All fae creatures will be distrustful of a human wearing this charm, but it is most commonly used by those going to battle against faerie monsters that have entered the mortal world and must be slain or driven back out.
The base cost is one strain, and the base difficulty, d4, for the ceremony to knot one thread. More threads may be added; for each additional thread beyond the first, the cost is one more strain than the previous. (E.g. using four threads total costs 1+2+3+4= 10 strain total.) For each thread, +1 is added to all saves against harmful or unwanted magics cast by fae upon the protected mortal. Each time such a roll is made, successful or not, one thread becomes useless and must be replaced.
