Just here to share with those who wish to add this to their mount collection
Note one of the keys Cyclonic Runekey does not only drop from the rare but can be FISHED up behind his spawn point by fishing in the open waters. This is not said on wowheads. Takes about 5min to fish it up.
For Torrential Runekey I sggest you join a group in the group finder there are currently plenty going so get into one now before the island dies.
Got mine today and was rather surprised and how quickly I got all the keys. Expected them to be an even lower drop rate but then here I am with my mount.
I got my mount yesterday, Torrential Runekey was the most time consuming part, about 2 hours of skeleton farming in a group. Overall it takes 4-6 hours to get everything you need, depending on luck. Not too bad, i expected it to take longer.
Im a little disappointed with the mount itself though, I know its a old mount that has been laying dormant in the game files for like 10 years, but they could have taken a few minutes to update it a little, the animations are very stiff.
