Koracks resemble a congealed blob of skin and mucus. Light bronze in colour, they stand on four stumpy legs. They have great folds of skin over the top of their eyes, a flat tongue-shaped nose and no visible ears. Their backs are covered in hundreds of tiny spikes.
The Koracks are dim-witted and are easy to kill once you rid them of their tentacle. This poweful appendage hanging from their belly can crush and maim with stealth.
