Giant centipedes are venomous insectoids that hide in forests and meadows wherever they find cover. Common folk tell tales that dryads bred them in Brokilon, or that cutting one in half makes two, but that is superstition. In Blood and Wine they are common in Toussaint, where they feed on the creatures that eat shaelmaar droppings.
Combat strategy
Use Insectoid oil and silver. They are immune to blinding, bleeding and knockdown and resist stuns, so rely on steady damage, dodge their lunges and use Yrden to hold them in place.
