Newbie Helper:
Now you are ready to begin honing your skills in direct combat. Try hunting the bearded keltirs that run loose in the fields south of Einhovant's School of Wizardry. Retrieve four Keltir Fangs, a quest item found on dead bearded keltirs. Do this, and I will reward you.
You will find the bearded keltirs in the area indicated by the yellow dot on the radar, at the upper-right corner of the screen.
