It is unknown if this beast is the result of fiendish magical experimentation or just another demonic terror loosed upon the world.
The arachno-raptor is a swift moving predator that hunts in packs. Rarely alone, the arachno-raptor will use teamwork and clever tricks to capture and kill its prey. They are extremely smart.
Some arachno-raptors have learned to mimic human speech (like a parrot) to lure intelligent creatures to their doom.
Rare arachno-raptors have learned to read magic (by capturing and enslaving weak wizards) and have taught themselves spell-use. Their ability is generally no greater than a third level magic user. They can use wands and scrolls.
It can create webs once per day, as the spell. The webs dissolve in a week unless maintained by the arachno-raptor.
I could really see these guys being used as the main protagonist in a game. They could use their superior intelligence to domesticate other spiders, ally with humanoids (or enslave them) and pursue their own agenda. Throw in dark elves, illithids and the demon queen of spiders and you've got another faction to have fun with!
