Vampire invisibility persistance

Sosderosii

Does the vampire invisibility break just like the nightblade one, when dealing or receiving damage and all the other reasons or is it more persistent while activated?
And once it breaks and the character is still sprinting, does it activate right back or after 3 more seconds?

1. Yes, breaks when you'd expect it to.
2. Instant break on sprint ending.

It also breaks when falling unless you jumped

The invisbility ends when you stop sprinting or when you receive damage. NPCs can also knock you out of it as they always do when you cloak right in their face.

Dealing damage does not always reveal you. I can for example be invisible with this passive while sprinting around enemies and zapping them with my boundless storm. Which is something I can not do with invis potions. That combined with the fact that it is the only invisibiliy that allows sprinting, it is quite a unique invis that is unlike any other.

Once you get revealed, you must stop sprinting and then start sprinting again. If you keep on spriting after having been revealed, you can not go invisible again during the same sprint.
