Spikebacks are large, hunched, animal-like humanoids of low intelligence and wicked disposition. They are so named for the lethally sharp bone spikes growing from their backs, which are remarkably effective in dissuading larger beasts from feeding on them.
These monsters do not actually employ their spikes when hunting, instead attacking with claw slashes and bites. Although the attacks are terrible in themselves, bite wounds from a Spikeback often infect the victim with a disease known as ‘meat-rot’.
Here are their game stats:
Spikeback (#Enc 1 or 1d6): HD 5d8, AC 5, MV 12″, SV +5, bite (melee Atk +5, 1d8 + meat-rot) / 2 claws (melee Atk +3/+3, 1d8/1d8), 500 XP. Meat-rot (victim cannot regain hit points until disease is cured, fortitude save to resist).
Individual Spikebacks often possess additional mutations (3-in-6 chance).
Spikebacks hunt either alone or in small packs of up to six members. While highly territorial toward other animals and humanoids, they are strangely tolerant to other, unfamiliar Spikebacks.
