I've noticed that when Hiravias casts the Firebug spell, it consistently does about twice as much damage as the in-game description says that it should (see screenshot in Dropbox).

 

So, for example, my build of Hiravias is supposed to do 48-61 points of burn damage according to the spell description, and yet when it hits enemies (I don't mean crit), it always does at least 100 points of burn damage. This often kills a lot of otherwise difficult mobs, and makes the spell over-powered.

 

Is this a bug?

well, is a fireBUG, (sorry have to make the joke)

I ve tested it in my game and its working as intended

Same here. It's so efficient that I refrain using it because it trivializes even the toughest battles. I'll try to post a screenshot of the issue soon.
