And: Is there a way to see how does vengeance works? (a url video would be nice, TQTQ)

If you use the search function, there's a thread when GMS tespia came out. Within those 70 pages, there is an SP user who specifically mentions how vengeance works and what it's animation looks like.

However, if you're too lazy, all it is is a polished up ninja storm (yeah the NL skill) that works for magic and physical attacks. You take the damage--> vengeance--> if works, damage is applied + stun + knockback. If not work--> monster just stays where it is. Also, it has a pretty purple light thing above your head that looks like a star.
