The main problem for Vyragosa seekers like me is that she shares a spawn timer with the highly desired Time-Lost Proto Drake, in fact I have seen it written in many places that "Time-Lost Proto-Drake is a rare spawn of Vyragosa" making TLPD a rare spawn of a rare spawn. Is that rare enough for you? TLPD has a 100% chance to drop Reins of the Time-Lost Proto-Drake.
A number of sources say that the spawn time for Vyragosa is between 6 hours and 24 hours. So I should pop in every hour looking for a spawn I guess! Geez, if that doesn't hike up my /played I don't know what will!
Draewind has a great page about Vyragosa and TLPD. If you look at the spawn paths on Wowhead and with NPCScan it looks like a windy mess, but Drae has actually made a nice map with paths, directions and spawn points.
|NPCScan path of TLPD/Vyragosa|
|Wowhead spawn points map|
|Drae's map with paths and spawn points (triangles) - every path except green one is anticlockwise|
There is only one person in the guild I know of who has TLPD - Roshii. Here he is on that elusive mount.
Boring bit ensuing - don't read on, it's just for my records!
21/8, 0753 - logged in to find Vyra dead in front of me near Valkyrion. How annoying! I logged in at 5 and 6 am and looked after kids at 7. Crap.
29/8, 0707 - didn't spawn at my camp spot near Valkyrion so I flew around and found Vyra dead on yellow flight path just cresting the hill.
2/9, 1500 - Aio gives me :( when I login. He says that he just killed Vyra 2 hours ago... I was just logging off then! Crap! But grats Aio!
