Question

What are the actions or circumstances that can make me stop riding my selected mount involuntarily?

Sometimes it happens but I don't always pay attention why. Of course, I am not talking about when I actually select to stop using my mount.

Answer 1

If you go invisible, swim, transform, or anything else that changes your appearance, you will be automatically dismounted. Also you can not ride your mount at protection zones.

Answer 2

There are a few spells / attacks that transform your character into another creature or object. After the duration of these spells your character will come back not riding your mount.

For example: A medusa has a spell that transform you to a statue for a short duration. When the effect is over you won't be riding your mount by default.

Answer 3

If you use a stealth ring or use the invisible spell, when some creature throws a changing appearance on you, if you swim it will disappear, if you enter any protection zones, if you use a costume bag or a “utevo res ina” spell and when you die
