Special Traits

  • Magic Scent. The thaumaturmite can pinpoint, by scent, the location of any magical cloth within 30 feet of it.
  • Consume Magic. Any magical cloth that the thaumaturmite hits starts to corrode. Each time the thaumaturmite bites into a magical cloth which is worn or carried, the bearer of the item must make a successful DC 12 Dexterity saving throw or the item starts corroding. After two failed savings throws the item loses its magical qualities.
  • Spider Climb. The thaumaturmite can climb difficult surfaces, including upside down on ceilings, without needing to make an ablity check.
  • Magic Resistance. The thaumaturmite has advantage on saving throws against spells and other magical effects.


  • Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 25 (5d8+3) piercing damage.
