While these creatures aren't meant to be fought (1 might make you guys nice and squishy..and theirs like 6 standing around where you guys are)...even though Tara seems to want to jump in.  The creature that grabbed you, has an interesting looking ring made of what appears to be bone.<br/><br/>Your actions as previously described were noted, as for my description of how he grabbed you...while a tad vague, it accounted for the fact that he can see you.  And his "buddies" could also see you while he had you held.  But since he threw you, you can disappear again from their sight; and the one that grabbed you 1) just got hacked into by Tara so isn't happy with her so 2) both he and his "buddies" are paying more attention to Tara than trying to look for you.  So while the one may have some sort of trinket that allowed him to sense or find you, he isn't paying much attention and wants Tara's head on his spear.
