When I right clicked this spawn to port up to Agnarr, a vendor opened for me...(<<was scratching head in confusion). Happened today on The Rathe server.../bug reported..hopefully they'll fix this lil problem. As a side note, this mob despawns with Askr, which means if u go AFK or LD and Askr despawns, you will have to gate out. I had 3 of these up at one time (after repeated conversations with Askr to get a functioning portal)...all of which served as duplicate vendors of the 2 items I sold (odd bug indeed). Apparently Askr is a cloner as well? Go figure.
After killing the Agnarr second floor mini-boss askr the lost spawns by the platform you came into rooom on. DO NOT hail him until you are fully ready for Agnarr, Jolur Sandstorm, the portals and 2-6 extra mobs. Hailing Askr, I am told, starts the portals spawning mobs.
To spawn the chaotic vortex you must do some dialog with Askr.
Heres where my information gets shaky. Once a chaotic vortex is spawned my guild tells me to target him and press U. I cannot get this to work. I'm not sure why either. The first possiblity is that the mob has been turned but lacking a way to tell I simply hail, run around, click him and the floor like a mad man. Sorry I can't supply the correct method here.
