Today we continue our look at the spawn of the Far Realm with the gibbering mouther, a weird and horrifying denizen of places no one in his or her right mind would go, and where no one stays in his or her right mind for long. An oozing blob dotted with mouths full of teeth and horrifying noises, the gibbering mouther offers an interesting analytical challenge, as its stat block looks unlike anything we’ve examined so far.
The gibbering mouther has average Strength, very high Constitution and low Dexterity, an atypical ability contour. It’s not strong enough to be a brute, it’s not fast enough to be scrappy, and it has no aptitude for stealth. Its low Dexterity suggests that, since its ability to avoid damage is poor, it will need some kind of compensatory advantage to make combat worthwhile, and simply being able to soak up damage isn’t enough; we’ll have to look for this advantage among its other features.
Its mental abilities are typical of an animal: average Wisdom (reflecting little except its perceptive ability), low Charisma and very low Intelligence. Entirely instinct-bound, it makes no distinctions of any kind between potential targets; one is as good as another. It may sometimes retreat when injured, but that’s the extent of its ability to adapt to changed circumstances. (more…)
