5E D&D Gamma World Monster: Gremlin
  This is the latest entry in a series of creatures I converted for Fifth Edition Dungeons & Dragons to be used in my son's new Gamma World hexcrawl campaign. You can download all 150+ monsters here
This small, hairless monkey eyes your mechanical items with intense interest.

Just as there are all kinds of genetically engineered creatures to "fix" the apocalypse, gremlins were engineered to prevent it. They were too late, but their mission has not changed: destroy all mechanical artifacts. As such, these hairless monkeys are very good at what they do, disrupting the effectiveness of all objects they can get their hands on. Intelligent robots and androids kill these creatures on sight, but gremlins are adept at avoiding detection, which makes them difficult to kill.

Gremlins thrive in ruins and cities where technology is prevalent.

  • Touch. The gremlin causes a Tech II or   higher object it can see within 5 feet of it to malfunction. If the object   isn't being worn or carried, the touch destroys a 1-foot cube of it. If the   object is being worn or carried by a creature, the creature can make a DC 13   Dexterity saving throw to avoid the gremlin's touch. If the technological object   touched is armor being worn or carried, its takes a permanent and cumulative   -1 penalty to the AC it offers. Armor reduced to an AC of 10 or a shield that   drops to a +0 bonus is destroyed. If the technology touched is a held weapon,   it malfunctions as described in the Curse Technology trait.
