Gibbering Mouther

by mshrm

One thing I’ve really noticed about converting old D&D monsters is that Gygax must have really, really hated his PCs.

Ok, ok, I jest, but still… this thing is a nightmare. Literally. It’s the one where some terrible thing is approaching with malicious intent, and no matter how hard you run, you can’t get away. First, it confuses it. Then, it blinds you. Then, it turns the very earth beneath your feet to quicksand. Just to add insult to injury, it’s so slow it’ll never catch you unless you’re a dwarf in your own weight in arms and armor… or unless you’re disoriented, blind, and unable to run at all.

Note that along with being Homogeneous, the mouther takes half damage from crushing attacks.

The Gibbering Mouther Training skill is a takeoff of the Slayer Training power-up, which is itself just a version of Targeted Attack. The gibbering mouther likes to aim its acid spittle at its victims’ faces, hoping to score a blinding wound.

  • Bite (13) 1d+1 cut, Reach C
  • Gibbering (Emanation) The mouther’s gibbering affects any creature that can hear within an 8 yard radius. Victims must make a Will-2 roll or gain the Disadvantage Confused, with a Self-Control Roll of 9. The mouther gets one attempt per victim per hour.
  • Acid Spit (14) 1d cor, Acc 0, Range 10 jet
  • Improved Grab: If the mouther hits with a bite attack, it may immediately attempt a grapple against the same target as an Extra Attack.
  • Engulf (ST vs ST/HT) If the mouther hits with a grapple, it may attempt to engulf the victim with a Constriction Attack with the Engulfing enhancement. An engulfed victim will be affected by digestive acids, doing 1d cor with Cyclic, 2 cycles of 10 seconds. Victims are also affected by blood drain, doing 1d-3 Fatigue damage each second.
  • Ground Manipulation (Emanation) The mouther can cause nearby stone and earth to become terrain similar to quicksand. This acts as a ST 12 Binding, Environmental (must be touching the ground), Engulfing, which lasts for 10 seconds.

Edit (14 April 2014): Upon reflection, I realized that despite having many eyes, the gibbering mouther shouldn’t suffer from the side-effects of injury to the eye, like blindness, precisely because it has so many replacement eyes. Thus, I have added IT: No Eyes.
