Refer to Agnarr Access Quest. Once you get the key (or know someone with a key), you go to the courtyard, use the key on the center lightning thing, then for a few secs, the group can click it to port into the first trial part of Ag`narr.
Was hitting me last night for between 2k and 6k, but seemed to be in the middle the most. lvl 80 gimp ranger now has a new bow, SWEET. Now need to get headshor maxed.
