I just changed the name of the topic if it hurt you feelings. Yes man. It really sucks to know that I didn’t figured that out myself 
Next time I’l try to do as much research as possible myself before asking. Feeling like a pussy but I wanna be a hardcore player and I am playing on hardcore, veteran settings. Hopefully I didn’t spoiled the gaming experience for myself with the secret knowledge learned via the community forum.

I mean, I was a bit confused by Vindictive flame when I first started playing, but then I just observed an explosion effect happening around my character when it got hit. Cool stuff huh?
Yep. I noticed that effect too but I thought that it was only due to fire retaliation which was indicated on the page three of the character’s specs. Fuck that but after tqFan wrote about this skill I started to experiment and learned that the fiery damage is the way bigger than just an ordinary retaliation effect. And that’s how I understood how it works. Feeling dumb
I still believe that their a huge room for improvement regards to the game’s documentation. They should make everything more clear in their game’s guide and inside of the game’s tooltips (put some sheets for comparisons and for more demonstrativeness for example). Though I absolutely believe that Crate made a very good guide for the game and especially when you think that only a small team made a game which is better than Diablo 3 for many people and for me it is better than Path of Exile and I see a lot of efforts they put in this game. I think that they really love what they made because you can’t make something that good without loving what you doing.
