Just spreading the word for those interested. The Serenade snail recipe was finally found today by someone on the secret discord. It’s in the first room of the Sepulcher raid. There’s like one trash pack, but you can run straight through and ignore it.
Down in the water sitting on a chain next to a big bufonid. 
Aww him coot snail… not as bootiful as mah piggeh but still coot.
These are the things that we need to know!
Snail Mount? …
*Neverending Story Intensifies*
They all aggro’d on me, and ported down to the snail lol. I’m trying out different things now though :D. TY for info.
Oh yeah they did that to me too. I just managed to grab the recipe faster before being murdered xD An invisibility potion might work I guess.
Are there pre-requs to being able to see the recipe?
Does the snail fly?
You do need to have the mount forge unlocked and that questline completed. No mount recipes will appear anywhere until then
OK cool ty
Only into our hearts 
Got it. Lucky me had the materials to make it right away.
i want a Human mount
Asana is the best 
It shall be mine
Is the mount forge different from the pet forge?
Different forge. You need Sopranian Understanding in the cypher tree and then there’s a questline to unlock it
Ok thank you
OMG WANT!!!
(vibrates with excitement and bookmarks page for later reference)
I assume one can stealth past the trash pack??
