On test server was posted that it will be like that:
- 10% chance to tame
- 5% to break item
- 35% fail but you can try one more time
- 50% monster is running away (disappear)

From my experience and my friends I can tell you that we had problems with cuz this Manta Ray love eats our Foxtails, I had to use 3 of them, my friend used 3 and didnt get mount just lost items another friend lost 2 items and didn't try again.
Was also problematic cuz she eat a lot of my reins like 3 per character on 4 chars.
Hibernal Moth That mount was crazy for me cuz I used lantern on around 150 moth before I tamed it :/
In 10h of hunting on Warzone 6 and trying tame it during hunt I didnt get that mount yet.
This mount might be problematic to tame cuz he cant eat your rune but if u fail u have to wait 20h to use it again. With 1 item I was trying catch this mount for month.
I guess and are easy to tame cuz never had problems with them. "Note that the Tin Key may break when used. The Tin Lizzard may also break, but the key is kept. The Lizzard will repawn a few hours later." - https://tibia.fandom.com/wiki/Tin_Lizzard
Is like RNG cuz sometimes you can use 3 sugar oats and get that and sometimes you might use 200 of them and still didn't tame that. xd but fortunately it can't disappear.
Ursagrodon is different also. https://tibia.fandom.com/wiki/Melting_Horn/Statistics
