A wizard\xe2\x80\x99s shackle can automatically detect the location of any active spell or magical item within 30 feet not hidden behind 10 feet of dirt, 5 feet of stone, 1 foot of common metal, or 5 inches of lead. \n'b'  Magic Resistance . The wizard\xe2\x80\x99s shackle has advantage on saving throws against spells and magical effects. \n'b'  Actions \n'b'   Bite .  Melee Weapon Attack : +3 to hit, reach 5 ft., one creature.  Hit : 3 (1d4 + 1) piercing damage and the wizard\xe2\x80\x99s shackle attaches to the target. While it is attached, any time the target attempts to cast a cantrip or spell, it takes 10 (3d6) psychic damage and must make a DC 10  Constitution  saving throw. On a failed saving throw, the target fails to cast the spell and if a spell slot was used, it is wasted. The wizard\xe2\x80\x99s shackle can be removed as an action by the target or another creature. If a creature or creature to which the wizard\xe2\x80\x99s shackle is attached attempts to remove the wizard\xe2\x80\x99s shackle, the attached target must succeed on a DC 13  Constitution  saving throw. On a failed saving throw, the target is unconscious for 1 minute. \n'b'  About \n'b' This tiny creature appears to be a gray-green leech. \n'b' The wizard\xe2\x80\x99s shackle is a 6-inch long, leech-like creature. Though it is small in size, it is greatly feared by spellcasters, for its bite drains arcane magic from a caster\xe2\x80\x99s mind. In some rare instances, evil spellcasters have harvested these monsters and set them loose in an enemy spellcaster\xe2\x80\x99s tower or laboratory. \n'b' A wizard\xe2\x80\x99s shackle attacks from ambush. It favors hiding on ledges, bookshelves, doors, and other such places where it can drop on spellcasters that pass underneath it. A wizard\xe2\x80\x99s shackle injects an anesthetic when it bites, so it is possible that its bite goes unnoticed (DC 12  Perception  check to notice).'
