Beware the Jabberwont, my friends!
The wont that speaks, the jaws that jab!
Beware the Hatfright too, their ends
Would much like your ends to grab!
Jabberwont: Init +7; Atk 2 claws +8 melee (1d8+7), bite +8 melee (1d12+7), tail slap +8 melee (1d20+7); AC -3 ; HD 7; hp 49; MV 50′ fly 100′; SP breath weapon 60′ 17 DC (physical body permanently warped, save vs. spells), nonsense 17 DC (charm, save vs. mind), immune to charm, immune to illusion; SV Fort +5, Ref +3, Will +7; AL CN.
Huge, malevolent dragon-like creature that can appear in areas where the walls between realms are the thinnest. The Jabberwont is about 20′ tall and covered in a combination of scales and thick feathers, the colour of both shimmer constantly in garish combinations. The Jabberwont is highly intelligent and will immediately begin gibbering nonsense when confronted.
The Jabberwont is an impossible creature and will disappear into nothingness if successfully confronted with this fact; if defeated in this manner, The Jabberwont’s hoard will also disappear.
Janelle Shane created a list of D&D monsters that was generated by her research into neural networks (http://aiweirdness.com/post/172170729017/dungeons-and-dragons-creatures-generated-by). James Holloway (http://gonzohistorygaming.blogspot.com/) ran a contest to create a monster from that list of names. This was my second entry, based on Lewis Carroll’s Jabberwock.
