Questions about Vendetta talent

1. Does it work on world boss or boss raid?

2. What kind of counterattack does it do? A simple physical attack for little damage?

Looking at the description, it seems to be a good talent, but is it as good as it looks?

Thanks

It does a fixed amount of percentage max health damage. Just a small amount though. So no matter how much damage you do it, the damage reciprocated doesn't change.

In all, good talent for tanks. Otherwise, no so. Doesn't work on world boss too

Does it work on world boss?

I see that Gryphion and Sphriex both have that talent. Does that talent works well on those 2 monsters?

Thanks

Not really both of them aren't really that tanky. For setanic it's quite okay though

its a very good talent against any frenzy user, you basicly kill you're self

This skill doesn't deal fixed damage. It is not based on percentage of maximum health. Weaker monster is even k.o by vendetta at the first attack.

Everyone just wants Sphierx with Doom Mark talent and Foresight skill. However, Foresight actually doesn't work all time. That's why I decide to choose Vendetta talent. I found out that the stronger my Sphierx is the better damage Vendetta deals.

Anyone share your experience ....
