Monster Name: Spear Spiderling
Due to spear spiders' speed and unique method of attack, very brave (or very foolish) swordsmen and women, particularly members of the Fangs, have traditionally fought them for sparring practice. Today, this tradition is hardly followed by any but the most rustic and rugged warriors-in-training. The spear spider is also known as one of the boldest arachnid hunters, as it tends to rely less on its webs and more on its barbed legs to capture prey. As a result, this species ventures further from its nest than most other spiders.
