Whoever designed favors didn't do us any favors. Even if it was a 100% 1 x per end boss chest in EX dungeons (like it was in 2.x) then it would keep the price high while allowing for dungeon farming incentives.
I've seen them drop from the chest once xD only 1 item
Low drop rate. Only ever 1 at a time. It would have been fine if it was a guaranteed drop but no, more pointless padding to force certain groups of players to replay old content over and over again.
Seen a Sky Spring Water drop from Neverreap a few weeks ago. never seen anything else after that.
I've seen one ever.
I've seen them a couple of times.
Purified Coke I've seen 3 or 4 times.
Sky Spring Water I've seen once (and got it in the lot).
Raziqcoat and Dryad sap I've also only seen once each.
Drop rate is still low... it's annoying
